ABSTRACT:
Polycrystalline silicon carbide with increased electrical conductivity at room temperature is produced by shaping a particulate mixture of .beta.-silicon carbide, boron additive, beryllium carbide and a carbonaceous additive into a green body and sintering the body producing a sintered body having a density of at least about 85% of the theoretical density of silicon carbide.
