Abstract

A process for forming a shaped body of silicon nitride having a transverse rupture strength greater than 2812 kg/cm2, characterized by the steps of compressing fine silicon powder to a crude density of at least 1.40 grams/cm3, the starting silicon powder being essentially free of particles having a diameter greater than about 10 microns, sintering the compressed powder in an atmosphere essentially free of nitrogen, carbon and oxygen, and thereafter calcining the product in an atmosphere which Contains nitrogen to convert the product to silicon nitride.
