Boron carbide powder is a starting material for sintering and hot pressing in the manufacture of boron carbide sintered parts. In this form it can be found, among other things, in dressing and grinding stones and as a lining for ball mills and mortars. Boron carbide powder is also used as a sintering additive for high-performance SiC ceramics.

Deformation features of the boron carbide lattice treated in a planetary ball mill are studied in our work. It is shown that such treatment causes a decrease in the B 4 C grain size and cracking along the {20 2 ¯ 1} h planes, whereas the same treatment in the presence of silicon results in the appearance of twins along the {10 1 ¯ 1} h planes. Distorted stacking faults along …
