Study on Al2O3-ZrO2 Ceramics with High Modulus of Rupture and Thermal Shock Resistance

摘要：

　　High Modulus of rupture (HMOR) and thermal shock resistance (TSR) are the main properties for high-temperature ceramic material.In this paper the HMOR and TSR of Al2O3-ZrO2 ceramics and its preparation are studied.It is shown that:Modulus of rupture of Al2O3-ZrO2 ceramics decreases gradually with increasing temperature.Increase of cracks caused by thermal shock in ceramics results in grain boundary widening and porosity increasing.As a result,the strengths of the material at mid-temperature and at high temperature are reduced increased,and the strength at mid-high temperature is reduced.The microstructure plays an important role in the thermal shock resistance of ceramic materials.
