The analysis of technologies for the synthesis of aluminum oxynitride (AlON) used for
the manufacture of transparent armor ceramics was performed. It is shown that the most
effective method of liquid-phase synthesis of AlON, where the fusion process is not aligned
with separately synthesized sintering,and raw material extends the technological capabilities
of production. It was experimentally established that more promising is the method in which
synthesis was carried out according to the scheme consisting of preparation of dehydrated
gel, its thermal decomposition, followed by nitriding in ammonia medium, wherein inorganic
material was used as a raw material powder synthesized beforehand. Application of the
technology can be used in manufacture of the whole range of products made by ceramic
technology methods - molding and sintering without pressure, and it allows obtaining some
shaped articles, e.g. transparent thin-walled shell which is used in rocket engineering.
