Method for nanopowder production boron nitride and titanium diboride

摘要

1. A process for preparing nanosized powders and boron nitride titanium diboride, as a result of plasma-chemical reactions of the starting reactants, characterized in that the plasma-chemical reactions initiated by pulsed microwave discharge in a contact metal-semiconductor or metal-insulator acting on the starting reactants, which are used as a mixture of powders of titanium and boron in a nitrogen atmosphere, the starting reagents are used amorphous boron powder with a particle size of 1 micron - 100 microns and the titanium powder with a particle size 1 micron - 100 microns, wherein the used microwave discharge capacity from 50 kW to 500 kW and a pulse duration of from 100 to 100 · 10c · 10c and the operating pressure of nitrogen is 0.1 to 1 atmosfery.2. A method according to claim 1, characterized in that the powder mixture contains from 10% to 30% titanium (by volume).
