PROCESS OF PRODUCTION OF INORGANIC MATERIALS UNDER CONDITION OF SELF-PROPAGATING HIGH-TEMPERATURE SYNTHESIS Russian patent published in 1994 - IPC

FIELD: chemistry. SUBSTANCE: process lies in that mixture of starting components of reaction state is put into reaction chamber, gaseous atmosphere is forced into it, synthesis reaction is initiated by means of igniting composition, mixture is cooled and products of synthesis are recovered. Combustible mixture of gases which concentration of components corresponds to conditional gas detonation is used as igniting composition and gaseous atmosphere. For instance, in case of use of combustible mixture composed of oxygen and hydrogen their relationship is from 0.77: 0.23 up to 0.15: 0.85 under filling pressure from 1 to 125 kg/qu. cm. For production of materials with coats reaction mould is made composite, one of its parts being blank for coating. EFFECT: provision for automation of process, reduced power consumption and increased quality of products of synthesis. 4 cl
