Abstract

A sinterable powder comprises: a) a particulate ceramic material e.g. SiC having an average particle size ranging from 0.10 to 2.00 microns and a surface area between 5 and 20 m<2>/g. b) a carbon source material (e.g. sugar or a phenol-formaldehyde resin) which will provide between 1.0 and 4.0 percent by weight of said ceramic material during sintering, and c) a residue from a solution of H3BO3, B2O3, or mixtures thereof as sintering aid, substantially uniformly distributed over the particulate portion of said powder to provide from 0.3 to 5.0 percent by weight of boron based on the weight of said ceramic material during sintering. d
