ABSTRACT:
Si.sub.3 N.sub.4 ceramics exhibiting densities and modulus of rupture values heretofore obtainable only by hot pressing are produced by pressureless sintering of powder compacts of partly amorphours, partly crystalline Si.sub.3 N.sub.4 powder containing between 5 and 60 percent by weight of crystalline material.
