Abstract

Brittle non-metallic powder materials such as ceramic oxide and silicon are mixed with an epoxy resin, a hardener and an organic solvent, dried, compacted and sintered to volatilize the resin. In the example, minus 60 mesh silicon powder is mixed with an epoxy resin, acetone and a hardener, dried, screened, compacted, cured at 50-250 DEG C. and then sintered in nitrogen to form silicon nitride bodies.ALSO:Brittle non metallic powder materials such as ceramic oxide and silicon are mixed with an epoxy resin a hardener and an organic solvent, dried, compacted and sintered to volatilise the resin. In the example minus 60 mesh silicon powder is mixed with an epoxy resin, acetone and a hardener, dried, screened, compacted, cured at 50-250 DEG C. and then sintered in nitrogen to form silicon nitride bodies.ALSO:Sintered silicon nitride is produced by mixing silicon powder with an epoxy resin, a hardener, and an organic solvent, e.g. acetone, then drying, compacting, and sintering in N2 to volatilize the resin and form silicon nitride. In the example, the particle size distribution of the Si is specified, and the compact is cured at 50-250 DEG C.
