METHOD FOR PRODUCING NANOPOROUS BORON NITRIDE Russian patent published in 2017 - IPC C01B21/64 C01B35/14 B82B3/00 B82Y40/00

Abstract RU 2614007 C1

FIELD: chemistry.

SUBSTANCE: reaction mixture is prepared of boric acid and magnesium nitrate, taken in an amount providing the cation ratio B/Mg in the range of 5-20, by means of dissolving in distilled water, and then the reaction mixture is heat-treated in ammonia at the temperature from 800°C to 1200°C. The invention allows to obtain boron nitride with a high specific surface (up to 1600 m²/g) and the pore size in the range from 2 to 100 nm.

EFFECT: improving the desired product properties.
