ABSTRACT:
A silicon carbide sintered body exhibiting N-type semiconductivity is produced by shaping a mixture of .beta.-silicon carbide, boron additive and a carbonaceous additive into a green body and sintering the body in an atmosphere containing nitrogen to produce a sintered body having a density of at least about 90% and pores which are substantially non-interconnecting.
