A process for the production of silicon nitride ceramics comprises the preparation of mixture of SiNfiller with additives of AlOand YO, mixing with self-set binder, production from mass of articles and their burning at mentioned temperature. As self-set binder hydrolyzate of organoelemental substance or ethyl silicate is used. Hydrolysis is carried out by the quantity of water, more than stoichiometric with catalyst hydrolysis of HNO. Products are made by the method of casting of thixotropic mass.
