ABSTRACT:
Tiny spherules of boron carbide having a diameter in the range of about 10 microns to about 125 mils, with a smooth, substantially spherical outer surface formed from the molten state by surface tension forces, are made by melting irregular particles of boron carbide or boron compounds which react with carbon to form boron carbide in an isolating medium such as finely divided carbon or boron nitride.
