摘要：

Refractory grade beta-Si3N4 powder was pressureless sintered with the aim of lowering cost. It is showed that beta-Si3N4 has good sinterability. A microstructure with small rod-like grains was obtained, which dispersed uniformly in the matrix, no abnormal rod-like grains was observed. The material displayed a strength of 587MPa and fracture toughness of 5.3MPa.m(1/2), which allow the material used in normal circumstance.
