摘要：

Ceramic composite crucibles failed when they were operated under extreme conditions of temperature and heating rate. To analyze the failure causes, fracture stress and fracture toughness values were ascertained and previously reported. Moreover, a new failure criterion for ceramics was proposed based on the existence of a crack-tip process zone. A probabilistic failure assessment curve was proposed to evaluate quantitatively the reliability of ceramics. By using the above data and theories, a fracture and severity analysis for crucibles has been completed. Some manufacturing techniques are proposed to improve reliability during service.
