METHOD OF OBTAINING NANODISPERSE POWDERS OF BORON NITRIDE AND TITANIUM DIBORIDE Russian patent published in 2014 - IPC C01B21/64 C01B35/04 B82B3/00 B82Y40/00 

FIELD: chemistry.

SUBSTANCE: plasmochemical reactions are initiated by pulse microwave discharge, influencing initial reagents, as the latter used is a mixture of titanium and boron powders in a nitrogen atmosphere, as initial reagents used is a powder of amorphous boron with a particle size of 1 mcm-100 mcm and a titanium powder with a particle size of 1 mcm - 100 mcm, the used microwave discharge has the power from 50 kW to 500 kW and a pulse duration from 100·10^-6 s to 100·10^-3 s, the working pressure of nitrogen constitutes from 0.1 to 1 atmosphere.

EFFECT: plasmochemical reactions result in co-formation of two target products - nanodisperse powders of titanium diboride and boron nitride of various shapes and sizes.
