Abstract

A powder of silicon nitride containing free silicon, or a body preformed from the powder, is sintered and isostatically pressed into an article, after first filling spaces between the powder particles, or pores in the preformed body, respectively, with nitrogen. When the powder or the preformed body, respectively, is heated, nitrogen and silicon combine to form silicon nitride
