TITLE., Techno logy for preparation of aluminium nitride and
the possibilities of-its comiercial use
PERIODICAL: Tsvetnyy6 metally, no#3, 1962, 56-61
TEXT: The aim of the p;9sent work was to establish the optimum
conditions for preparing aluminium nitride powder. The initial
materials were aluminium powder nA -4 (PA-4) with particle size
less-than 04042_- _-puriffed- nitrogen -containing a trace -of
oxygen, and ammonia. The
previouely, enabled material to be nitrided by passing nitrogen
over a boat containing the material. Experiments at 700 to.12000C
showed that after up to 240 minutes, nickel and zirconium boride
did not react- with -aluminium nitride-, -- - The -boats-
were therefore made from these materials. The rate of heating
has to be low enough to prevent fusion of the aluminium because,
if fusion occurs, tho surface area of the reaction is decreased
and the aluminium is more likely to react with the material of the

10*C/min or lower for the 0.042 mm powder. The optimum condItions
for nitriding were found by a serioa of experiments in a current of
nitrogen for 15 to 240 minutes and in a current of ammonia for
2 hours at 500 to 1200'C. The results showed that there is
relatively full nitriding of the finer powder at 7000C but the
coarser powder requires a temperature of 1100 to 1200%. From
the results the following scheme for production of aluminium
nitride was put forward.. PAK-4 powder is nitrided at 8009C for
I hour with a rate of increase of temperature up to 8000C of 10*C/
min. The prepared product is tharoughly mixed and a repeated
nitriding in carried out at 1200% for 30 to 60 minutes (with a

TITLE: Derivation of magnesium nitride
SOURM Zhurnat prikladnay khbdi, v. 37, no. 8, 1964, 1828-1830
TOPIC TAGS: magnesium, nitride, nitration agent, ammatiag nitrogen
ABSTRACT: The authors conduct a technological study of conditions for obtaining
magnesium nitride using nitrogen and astsonia as nitration agents. The initial
material consisted of magnesium chips measuring 0.1-0.2 mm. Nitration took place
'in porcelain vessels placed in a quartz reactor. Nitration was conducted at tem-
yeratures from 200 to IOOOOC over a period of 13 minutes to 4 hours for each temper-
.ature. The results of the experiment showed that nitration begins during the die-
.tillation of nitrogen through magnesium over-& period of 30 minutes at 2500C.
Nitration reaches its peak at SWC over a period of 4 hours. At higher tempera-
turee the nitrogen content drops sharply. The authors concluded that attempts to
nitrate magnesium with semonis have yielded much poorer results, which is apparently
related to the f &at that magnesium nitride converts easily into hydcide and

of 2.0 ml.. and 15-20 days later a 3rd :nJection (2.0 ml.) was administered. Re
vaccination was performed 3-6or 6-12 months later. It was observed that the level
of Immunity (as indicated by the Schick test) after 3 injections was twice as
high as that created by 2 inj ections. Furthermore in the case of the children who
received 3, injections the cli nical course of diphtheria was much milder, and to3dC
and malignant forms much less frequent, than in the case of the children who re-
ceived 2 injections only.

During 1946-46 the efficacy of antidiphtheritic Immunization with varying inter-
v-Als between the vaccination and revaccination was followed on 935 children. It
was found that extension cd the interval between the 2-stage vaccl=tion and re-
vaccination at 6-7 months enhanced the efficacy of the Immunization. Revaccinat-
ton at an interval of 6-12 months after the triple vaccination trebled its effective-
nose. The author advocates revacclAation at 6-8 months Instead of at 3-5 months.

changes in the level of diphtheria immunity occurring following an attack of an
Infectious disease were studied by means of Schick testing. The children In-
vestigatedhad been Immunizedonce only and before the age of 3. Schick testing was
performed on 1556 children who had suffered no illness duriag the preceding 6
months and on h77 children -who had suffered an infectious di3ease during that
period. In the former group 18.516 and In the latter group 27.2% positive reactions
were Wained. This percentage was even greater in the case of children who had
suffered an attack of an Infectious disease within a month Immediately preceding
tive Schick testing. (8)
