FIELD: chemistry.
SUBSTANCE: method is suggested for production of beta-sialon, in which thermal treatment of mixture of aluminium powder with specific surface area equal to 22.0-24.0 m2/g, and crystalline silicon powder with specific surface area of 0.2-0.3 m2/g, taken in the ratio of 1:1, is carried out by heating up to temperature of 1100-1200°C with heating rate of 10-12°/minute in air atmosphere.
EFFECT: method simplification at high yield of finished product.
