摘要： We had previously disclosed a heat resistive and reinforced composite material which was prepared by sintering a finely powdered mixture of trisilicon tetranitride and an oxide of yttrium group elements.More improved similar composite material having excellent bending strength can be obtained by sintering a finely powdered mixture of trisilicon tetranitride, yttrium oxide and aluminum oxide. Cerium oxide, lanthanum oxide or scandium oxide can also be used instead of yttrium oxide.
