ABSTRACT:
A mixture of reactants having a particle size of about 200 microns is heated to convert said mixture comprising a metal compound, carbon, and a boron source to a metal boride having an average particle size of about 0.05 to about 0.5 micron. Said metal compound is one which can be converted to the corresponding metal boride by reaction with carbon and a boron source under controlled conditions of time and temperature.
