ABSTRACT: The method of preparation of calcium-lead alloys based
on the reaction 3 Pb + CaC2 --&, Pb 3C& + 2C (Reaction 1)
was first developed by Kroll (Rei's 1-3)~ Many patented
p"cesses for the preparation of alloys of lead with
alkali and alkaline earth metals have been based on this
method mid most of the published data on the thermit
processes of this type are to be found in patent speci-
fication in which the theoretical basis of the process is
not discussed. The object of the present investigation was
to fill in this gap by establish-ing experimentally the
mechanism of the reaction between Pb and CaC2. In the
preliainary experiments the possibility of reaction (1)
taking place was verified. To this end, a small quantity
Cardl/9 of CaC2 was placed in a quartz ampoule which was then

SOV/149-58-6-8/19
On the Mechanism of the Reaction Between Lead and Calcium Carbide
partially filled witli molten lead (since lead wets easily
CaC2, the latter compound does not float on the surface
of the molten metal but is uniformly dispwsed throughout
its volume). On heating, the pressure in the ampoule
decreased to 0.1 mm Eg. The ampoule was then sealed,
placed in 6 vertical resistance furnace and maintained at
800 - 900 C for I hour. During this period the pressure
in the ampoule was reduced still further owing to the
presence of CaC2 which acted as oxygen getter- Only
0.5% Ca was found in lead after this treatment the
prpportion of Ca that had reacted with tj~:1L-,r -~n-iy
5.,6% of its total quantity present ic Ca,~'2 IL the
experiments. The fact that the MaCtIUL orr ;ea-i*4 to
such a small extent was attributed to the absence of
stirring, as a result of' which the rate of reaction was
governed solely by the rate of the diffusion processes. In
addition, the reaction was slowed down by graphite and
certain other impurities (mainly CaO present in CaC 2 in
Card2/9 quantities up to 30%) being precipitated at the interface

SOV/14q-58-6-8/19
On the Mechm-1 = of the Reaction Between Lead and Calcium Carbide
of the reacting phases. Consequently, in the next series
of experiments Fb and CaC2 were made to react in an open
crucible, under a layer of flux consisting of CaCl 2 with
a suall addition of C&P2 (whose function was to protect
the melt from oxidation and to form a slag with CaO and
graphite), the contents of the crucible being stirred at
the rate of 250-300 r.p.m. The experimental apparatus is
shown schematically in figure 1 where: 1) Kryptol

results are plotted in Pi ure 2 in the form of graphs

temperatures. The effect of the particle size of C&C 2 and
of the flux/Cac 2 ratlo on the curse of the reaction was
also investigated and it was found that, in agreement w-Aith
the industrial experience (Ref 6) -.he optimum values of
Card3/9 these parameters were 4-6 mm. for the carbide particle size

SOV/149-58-6-8/i9
On the Mocha-ism of the Reaction Between Lead and Calcium Carbide
and 2.3-2.5 for the flux/carbide ratio. To determine the
order of reaction 1), two experiments were cai-ried cut
in which, all the other factors being equal, two differen-,
quantities C 1 and C2 of Cac 2 were used. The values of
Cl and C 2 (in g) at the beginning of the experiments
and after 30 minutes at the testiamperature, their average
values over t4s period and the mean values of the rates of
reaction AC/Ot are given in Table 1. With the aid of
the formula on p 74, it was found fi-cm these datla that
reaction 1) is of the first order. The :or.*;ants ~~f ~ne

On the Mechanism of the Reaction Between Lezcy ano
alloy is quite possible owing to the fact that free
calcium combines with lead and affects the equilibrium
conditions of the system and that the halide salts used
in the flux act as catallsts (Ref 7). The set of reactions
proposed by the author for CaC 2 is similar to those
postulated by other workers for other farbido-thernit
processes. Thus for instance, Fak, Nyong-she and
B*llyayev (Ref 85 proposed the following set of reactions
for the reduction of NgO by CaC2
CaC2 Ca. + 2C
Mao + Ca Mg + CaO
fto + C&C2 Mg + CaO + 2C
Similarly, GeI'd et al. (Ref 9) considered thi vacuum
reduction of N&CI by C&C2 as a series of two consecutiv*
reactions: dissociation of CaC2 and reduction of IaCl by
Ca. On the other hand, 5riadadge and Pazukhin (Ref 10)
Card?/9 postulated that interactions between CaC2 and NaCl:

02 the N9Cb&SLi2Z Of the Reaction Between Lead and Calcium C&rbide

occurs by means of a direct exchange of electrons as a
result of interdiffusion of the reacting components
2- +
according to the equation C2 + 2Na a 2C + 2Navapour
(Reaction 2), the electric neutrality of the reaction
being secured by the migration of the Ca ions into the
molten chloride. While admitting that in the case under
consideration the direc-W interaction between Pb amd C&C2
is also possible, tte pTesent atuttcr considers tha* it car-
play only an insigri-fi7ant part. He states also that an
additional proof of his theory is provided bjv 'r."te fact that
when the carbido-thermit reaction taken place in NaCl, the
obtained alloy contains a definite quite appreciable
quantity of Ca, as is shown in Tabie 2, where the weight
of the flux (in g), its composition, weight of the alloy
(in g) and its composition, determined in three experiments',
Card'S/9 are given. If it is assumed that under these conditions

BOV/149-58-6-8/19
On the Koch--an of the Reaction Between Lead and Calcium Carbide
reaction(2) does in fact occur, the enrichment of the
alloy with Ca would be possible only as a result of the
secondary reaction 21a + CaC 2 ;� Ca + 2NaC (Reaction 3).
The results obtained by various investigators (Bets 11,12)
who had studied these processes indicate that the
possibility of reaction (3) taking place is exceedingly
small, while on the other hand the presence of Ca in the
alloy can be easily explained if the possibility of
dissociation of C&C 2 is accepted. There are 2 figures,
2 tables and 12 references, 6 of which are Soviet and

ABSTRACT: In this letter to the editor, the author comments on the
article by V.V. Rodyakin published in Tsvetnyye Metally,
1958, Nr 4, on the carbide process for producing lead
alloys. He notes that similar work was started at the end
of 1956 at the Noskovskiy inatitut tsvetnykh metallov i
zolota (Moscow Institute for hon-ferrous Metals and Gold)
in the *Litaynoye proizvodstvo" (Foundry Production)
laboratory under the direction of Professor Dr I.G. Spasskiy.
He contra*s this work and its results with those of Rodyakin
and suggests that available evidence (Refs 4,5,6,7)
indicates, contrary to Rodyakin's views that aluminium.
plays a ainor role. As reported (Ref 83, the laboratory work
at the Moscow Institute has been confirmed at the Podol'sk
Alusinium Works. He concludes by stating that further

ABSTRMTs So publications have appeared on the system of Pb-C& alloys since
1933. Only the alloys in the interval pure lead - Pb 3Ca compound
are of industrial interest (anti-friction, cabel, accumulator
alloys etc.). The authors investigated the character of the none
variant transition and solubility of Ca In solid lead at various
temperatures in a series of alloys containing 0,10 to 0.01 wt%
Ca. The Ca coatent was determined according to a method by
To. A. Meshnikova (Ref 7). ke the Ca addition produces only a
slight change in melting point, the method of zone melting,
originally proposed for the system Al - Nn by D. A. Petrov and
A. A. Bukhanova (A*fv 0, 9, fig 2) was applieds a melting zone,
produced by a high frequency inductor, was led over a 70 am long

then prepared and examined microscopically. The aicro-h&rdness
was also determined (Fig 4), and proved to be constant with the
exception of the initial (lower hardness) and the terminal
sector (greater hardness). The calcium content of the initial
sector had been lowered 'by the sone melting process, and that
of the terminal sector raised (Fig 3). Thermal analysis

crystall1sation upon the physical properties. In the case of quick
cooling, a metastable phase occurs, which form only in small quantities
In the case of very slow cooling. High conductivity and thermo-emf can
be attained only if the content of the metastable phase is very low. An
important part is also played by the degree of purity of the initial
materials. The branches of the thermocouples are produced by a method
developed in IPAN, which is not described in this paper. The physical
properties of the thermocouples were checked by means of a circuit, the
scheme of which is shown in Fig. 2. Table 4 gives data of thermccouples

TEXT: The basic materials employed were 99.999% pure indium
(brand VM-() (In-0)), 99.99% pure crystalline arsenic and 99.99% pwv
red phosphorus "used for semiconductors of class AV. The alloys
were prepared with the aid of a special furnace shown in Fig.2.
The furnace consisted of two parts. The left-hand part was
maintained at a high temperature and contained indium in a quartz
boat, while the right-hand part was kept at a lower temperature and
contained phosphorus and arsenic. This procedure has been A
described by the second of the present authors in Rof.5. The alloys-
thus obtained wore subjected to zone recrystallization as described
by 0. G. Folberth and K. Weiss (Rof.6). Chemical analysis of the
specimens was not carried out. The composition was chocked by
comparing the weights of the elements loaded into the ampoule and
the solid solution obtained in the end. The specimens wore ground
in an agate mortar until the average particle size was about 0.01 mm.

TITLEt Method for the graphite coating of quartz workpieces
PERIODICAL: Zavodskaya laboratoriya, v. 27, no. 2, 1961, 177-178
TEXTs To prevent a reaction between quartz and semiconductor materials,
the surface of the former is coated with a thin carbon layer. No exact
data on applying such coats are to be found in relevant publications. In
this paper, a method is described for applying carbon coatings on uartz
surfaces, which is based on a pyrolysis of pure organic compounds ~such as
acetone). The thermal decomposition of acetone prGcoeds most favorably at
7000C, C02' CE40 hydrogen, and ethylene being formed. The latter disso-
ciates and contains the complex anion (C-C) 2- , which easily polymerizes to
the graphite lattice. Since the separated carbon is in an active state,
it adsorbs well on the quartz surface. Heating the graphitized quartz
piece in vacuum apparently strengthens the quartz-carbon bond through
formation of silicon carbide, which was also determined microscopically.

Graphitizing takes place in a special apparatus which consists, in
principle, of a heatable quartz tube through which argon is conducted
serving as a carrier gas for the acetone vapor. Best results were
obtained at 7000C and a duration of 30 min. The graphitized object is
ignited in vacuum (0-05 mw Eg) at 1100-120000 for 2-3 hr.- There are

ABSTRACT: Stimulated emission of InP diodes in the 9060-9090 ; region wa3 compared
with that of their GaAs counterparts (see Table 1). InP bars were prepared by the
directed crystallization method in the form of large-size polycrystals graiined in the
direction of the bar axis. The bars were tellurium-doped with electron concentrationsl
of 5.1017 cz~-3. The diffusion of zinc from the gas phase into polished plates each
containing 2-3 seeds took place at 750C over a 30-min period. The depth of the p-n
junction was 35 p. The electrical contacts were made of gold which was sputtered on
plates at 400C. The bar ends were polished and the sides were roughly worked. The
GaAs diodes were prepared in a similar manner with the following exceptions: diffusion
of zinc into GaAs lasted 4 hr at 850C under excess As pressure, and the resonator

diffusion depth in both cases was almost identical. As regards the width of directi-
vity, InP lasers (5-7*) were shown to be superior to GaAs lasers (14-191 by a
factor of 3 or 4. UP laser diodes were characterized by a low lose factor (%7 cm-1)

and a gain relativel lower than that of GaAs, expressed in a linear approximation as
k - 3.4 x 10-3 j c*-T , where j (amp/CM-2) is the current density. The latter can be
due to a lower (than GaAs) quantum yield and to a thick active layer (8-10 U).
The differential efficiencies of the InP laser made it possible to deliver pulsed
e
power of 7 watts at 75 amp at the liquid N temperature. Orig. art. has: 2 tabl 8,

ABSTRACTt Hydrophilic sails cannot be used in road construction. Treat-
ment with bitumen and tar increases their hydrophobic nature.
The best effect is obtained by tri-valent cations, like iron
salts, which affect the colloidal-chemical properties of the
soils. The addition of iron salts reduces the quantity of
bitumen necessary of hydrophobisation. The iron sulfate@ and
chloride* are by-products of the metal industry and the
bromine plants.
There are 2 tables. and 5 Soviet references.
