Pressureless Sintering of Refractory Grade β-Si_3N_4 Powder and Mechanical Properties of the Sintered Materials
Source abstract
Abstract
Refractory grade β-St3N4 powder was pressureless sintered with the aim of lowering cost. It is showed that β-St3N4 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.m1/2, which allow the material used in normal circumstance.
