It is shown, that I in quite stable with icide. In dilute acids (1:1) possesses a very small solubility. I is also stable in alkaline - solutions of various concentrations when cold as well aB when heated and in the presence of oxidizers. A complete analyzing method of I is developed, which includes detection of the total and free B, Al, Si, Fet Ca-and--Mg. In determining the total B, a weighed portion of I is fused in a Fe crucible with a mixture of NaOH and NY 2.

For a complete analysis of I, a weighed portion is decomposed by melting in a Pt crucible. In separate aliquot batches of the solution the total quantities are determined of B end Fe (photo- metrically as thiocyanate), of Al (by photometric determination with Aluminon, preventing the interference of Fe by adding ascorbic acid), of Ca (by the oxalate method) and of Mg (by the phosphate method). The content in free C is determined from the time required to reach the constant combustion rate of I (G. 1. Meyerson, G. V. Samsonov, Zavodak. laboratoriya, 1950, 16, 1423). To determine the free B, a wiighed portion of I is boiled with a mixture of perhydrol and concentrated HNO 3 (1:2) in a flask with a reflux condenser for 30 - 40 min. The undissolved residue is filtered off and the free B pas aing into solution is determined by titration after adding mannite or invert sugar. [Abstraoteria note: Complete translation.

T-------------------------- TITLEs Photometric Determination of Nitrogen in Titanium Carbide and -Boride and Other Refractory Materials PERIODICALs Zhurnal analiticheskoy khimiip 1961, voi. 16, No. i, pp. 79-82 TEXTs In this work, the solubility in various organic solvents of the dye formed in the thymol - hypobromite reaction on ammonia was studied with a view to finding out condition3 under which the thymol-hypobromite reaction can be applied for the determination of nitrogen in titanium carbide and other refractory materials. The experiments showed that intensely colored extracts are obtained by using esters and alcohols as solvents. Of the eaters and alcohols investigatedp isoamyl acetate and n-butyl alcohol, respectively, were chosen. At equal nitrogen content, the latter solvent gives a much intenser color than ieoamyl alcohol. The absorption curves of the dye solutions in n-butyl alcohol and isoamyl Rcetate are shown in Fig. 1. The optical-density measurements of the extracts were carried out Card 113 Photometric Determination of Hitrogen in Titanium S/075/61/016/001/014/019 Carbide and -Boride and Other Refractory BO13/BO55 Materials in a universal f M(FM) Pulfrich photometer. The molar extinction coef- ficient of the dye in n-butyl alcohol is nearly 6 times that in isoamy! acetate. Thus the use of n-butyl alcohol considerably increases the measuring sensitivity. The optical density of the extracts must be measurei with a red filter (Aeff , 665 m,;4). The optimum pH for dye formation is illustrated in Fig. 2. The colored compound forms at pff 11 - 11.5, but the pH of the solution before addition of the reagents must be between 1-5 and 8-5, if the reaction is to proceed satisfactorily. In practice, this means that the acid solution of the test sample must be neutralized with caustic soda against phenolphthalein before adding thymol and hypo- bromite. When small quantities of nitrogen are to be determined, the precipitation of hydroxides during neutralization must be prevented by suitable additives. Chromium is masked best by oxalic acid# iron, titanium, and vanadium by means of potassium fluoride. Tests showed that with these masking agents, calibration curves taken in the presence of titanium, iron, chromium, and vanadium a.-e practically identical with curves obtained under the same experimental conditions, but with pure ammonium salt solution. In consequencep a standard calibration curve plotted for the Card 2/3 Photometric Determination of Nitrogen in S/075/61/016/ooi/(,14/019 Titanium Carbide and -Boride and Other BO B055 Refractory Materials pure ammonium salt may be used for the determination of all quantities of' d v nitrogen in eamples containing titanium, iron, chromium , d vanadium* rl-e 0 Basing on the experimental data obtainedv the authora works out a method t t in of determining small quantities of nitrogen (0.01 - 1~) in t anium \ carbide and titanium boride. Wherever possible, chemically purke reagents and bi-diatilled water for preparing the solutions should be usl,,d. The only differences between the determination of nitrogen in refractqry com- pounds containing chromiump iron, and vanadium as main constituent -a and the above analysis of titanium carbides and borides are the way in .V~ich the weighed portion is decomposed and the type of masking agent used "to prevent hydroxide precipitation.

T TITLEs Caking method in analyses of boron ~,arbide, boron nitride. and metal borides FERIODICALs Zavodskaya laboratoriya, v. 27, no. 11, 1961, '345-13,,6 TEXTa In the present paper, a method of decomposing boron carbide boron nitride, and metal borides by caking with CaO, MgO, and B&CC 5ha3 bQen developed, since the traditional methods (acid decomposition, melt iz-, platinum crucible, melt in iron crucible) have several drawbacks in mas.5 analyses. Platinum crucibles are not required for the new method The auth-ors found that a 40% oxidation of the borides of hardly fusible metals, and boron carbide and nitride, takes place with formation of boric, acid anhydride by 2 hr roasting in an open muffle furnAPA at 95OCC Further oxidation proceeds Yery slowly, since the particles coat vith the molten boron trioxide. This particle vitrification can be avoided and thv oxidation period reduced by careful mixing of boron carbide w:-th a Card 1/3 ,/61/027/0-1/003/0!6 S1032 Caking method in analyses of boron B1061B110 porous material,, For this purpose, the authors used CaO.

The .-esulting B 203 reacts with CaO to give calcium polyborate, Ca 2B011, which is practically insoluble in water. The cake thus formed has therefore to be dissolved in dilute hydrochloric aoid,. After re,~tridllza- tion with dilute sodium lye with methyl red as indizator, some aroy, ef hydrochloric acid are added until the IndAcator rechanges to red, "hen, a small amount of dry BaCO 3 im added until the color turn:i yalloor Thij golution is then heated to, and the depogit of admixtureg ii filtgred off and carefully washed with hot water, Much better resL.-3 a---r obtalned by caking with BaCO 3' In this process, the bcriflas of ha-Ily fusible metals are completely decomposed, and practically ali ~,oror. passes ~-nto the aqueous extract after treatment with wator, Wh 9 n t h e Card 2/3 S103 61/027/011/0012/016 Vaking mathod in analyses of boron ... B1069110 deposited admixtures have been filtered off, boron contained in this extract is determined by titration with lye in the presence of mannite or invert sugar. The above caking of metal borides, and boron nitride and carbide, with CaO or BaCO3 was conducted in nickel, iron, and porcelain crucibles. Unglazed porcelain crucibles proved best suitable for caking with CaO, and nickel crucibles for caking with BaCO 3 The cake can easily be removed from the crucible walls and taken out by shaking. The authors tested the above method of caking with CaO and BaCO, by comparative boron determinatioraby the abovu mothod and that of blulk ash.~ The good agreement of results proves the suitability of the described method for determining boron in boron carbide and nitride, and in metal borides.

S/'073/631018/004/009/015 On the basis of preliminary reduction tests of Nb with Al powder, Zn dust, Zn amalgam, metallic Cd, and in cadimum reducer at various acidities of the solution, a new method was established at the Institute of Powder Metal- lurgy and Special Alloys of the Ukrainian Academy of Sciences for the de- termination of TNbC and in mined carbides of the ZrC-iNbC type. The method is based on the reduction of Nib in the dissolved sample to the re- quired constant average oxidation number of 3.0 2 to 3 .0 4 by means of m e- tallic cadmiu,,-n and a cadmium reducer in a mixture of sulfuric and hydro- chloric acd!;. The reduced Nb is then oxidized to Nb(V) with a solution of iron arnmonium alum, and the Nb content is calculated from the equivalent amount o_11 bivalent iron formed)which is determined by titration with potas- sium bichrornate with phenylanthranilic acid indicator. The results are in agreement with data obtained from the gravimetric cupferron method. JEDW] Card 1/1 S/03 63/029/003/007/020 BI 17YB186 AUTHORS: Nazarchuk, T. ff., Kopylova, V.

Extraction of the cupronate with chloroform is therefore recommended for completel separating cerium from traces of Fe. 5-10 g nickel alloy (Cr-Ni-Fe~ is dissolved in a mixture of hydrochloric and nitric acids, filled up with 25-50 ml H2 s04 (1.84), and evaporated until 30 3 vapors are formed. The solution is diluted. Chromium is oxidized with ammonium persulfate in the presence of silver nitrate, Al, Fe, and Ce hydroxides are precipitated with ammonia, the precipitation being repeated. The hydroxides are dissolved in hot saturated oxalic acid solution with addition of 1 ml 5% calcium chloride solution, and left standing overnight at PH 4-5.

The resulting oxides are diamolved during heating in 10 ml H 2s04 (1:4) with addition of some drops of perhydrol. Then cupronate is extracted with chloroform. Excess cuprone is destroyed in aqueous fraction, and the cerium is determined. For this purpose, the colorless solution containing 1-2 ml H 2S0 4 (1-84) is mixed with 4 ml 0.1 N Trilon B solution and 10 ml glycerol, the solution is neutralized with NH 3 to a characteristic smell, 5 ml buffer solution (pH 9) and 2-3 drops of 30/6 hydrogen peroxide are added, diluted "ith water after 5 min, and the optical density is measured after 30 min. The oxidation of chromium and the filtration of the hydroxides can be omitted when determining cerium in cast iron of low chromium content.

The colour of the complex solutions obeys Lambert- ~Nb2 - H6RJ Beer's law in the range of niobium concentrations from 3 to 35 g/ml. An un- Usual effect of admixtures of NaF, oxalic, tartaric, and citric acid, and of trilon B on the colour of the complex solutions was observed. The ratio niobium: aAmixture was varied from I ; 0 to 1 : 25 and up to a ratio of 1 : 2 a strong increase of the colour Intensity was observed. Purther addition of the admix- ture effects a decrease of colour intensity. Tho composition of the Nb-arsenazo complex does not change, but in destroyed at a tenfold excess of the admixture. The following sequence in relation to the decreasing stability of the complex compound of 11b was observed: oxallc > fluoride -.~ trilonate -~- tartaric -.;~ citric acid. The initial increase of the colour of the niobium-arsenazo complex af- fected by addition of the admixtur-3a is explained by a transfer of niobium into a more reactive form. Apparently the monomer cationic form of niobium reacts vrith ar3enazo, %nd an addition of the complexing admixtures contributes to the fommation of monomer niobium ions.

Another series of experiments on 30 rats high in the mountains confirmed the above-mentioned assumption and it was found that oxygen supply to the brain was a major factor in the pathogenesis of convulsions.

Measurements were made of the body temperatures of alI rats. Part of the rata.were then killed and their brain, liver, and kidney Card l/ 3 ACCESSION NR: AT4042673 temperatures measured. In ten of the rnts, kidney temperatures were measured during acceleration. It was found that when rats were subjected to accelerations of 2 to 30 g the intensity of oxygen consumption increased. In contrast to animals with a large body mass (man, monkeys, dogs, etc.), in which external respiration is diminished when they are subjected to acceler- ations of 7 to 10 g, rats showed a significant increase in oxygen consumption, even when subjected to 17 g for five minutes. Body temperature of the rats rose after the eIeriments by 3 to 80 C and the temperature of the Internal organs by 3 to 5 C. Disruption of respiratory movements was observed in animals subjected to accelerations of 22 to 2G g for fifteen minutes. When subjected to 28 g, motor disturbances appeared during the first two or three minutes; when subjected to 50 g, they appeared during the first minute. When rats were subjected to a 50-g acceleration for one and one-half minutes, a statistically significant increase in oxygen consumption by brain tissue was noted. After prolonged acceleration a definite drop in the temperature of the entire body was observed, In some cases this drop was as great as 100 C. This phenomenon, which was designated "poot-gravitational hypothermy." was Card 2/3 ACCESSION NR: AT4042673 accompanied In the experiments by an increase in oxygen consumption.

This makes it posnible to ermloy ordirkir-j conmercial licraid nitrogen, and also to reload the samples and to vary their temperature in simple fashion. alic reason wlq liquid nitrog(~n cannot be u:-,ed for this purpose is briefly discussed. T'he cold nitrogen is fed from a liquid-nitrogen evaporator outside the reactor, flows th-ough the cryostat channel, and is drawn out by a ventilating system.!, If the liquid nitrogen contains -14, of argon, the activity of the radioactive Ar4l fdoes not exceed 9 millicurie/hr at a reactor power of 10 1.014. The construction of the !1 installation (Fig. 1) and the method of rranipulat1w, the samples are described. The channel described was installed in the M-M reactor in I-larch 1964, and apart from accidental loss of hermeticityp 'which was later elimimited, it withstood many tests with large temperatuare differentials.
