FIELD: chemistry.
SUBSTANCE: invention relates to powder technology and nonferrous metallurgy. The method of producing nano-size aluminium nitride powder with particle size of 10-150 nm and specific surface area of 30-170 m2/g involves feeding alumina powder with a stream of plasma-supporting nitrogen gas into a gas-discharge plasma rector at reactor temperature of 4000-7000°C, cooling the thermal decomposition products with a cooling inert gas and condensing the obtained aluminium nitride powder in a water-cooled receiving chamber, in which alumina powder - dust is trapped in electrostatic filters of aluminium hydroxide calcination furnaces when producing alumina. The disclosed method of producing nano-size aluminium nitride powder is characterised by cost-effectiveness since the starting material is wastes.
EFFECT: invention improves biocompatibility of implantation metallic materials.
