Effect of SiC on Microstructures and Properties of Cordierite-mullite Multiphase Ceramics Material

摘要：

In this paper, cordierite-mullite muitiphase ceramics material was prepared using cordicrite powder, mullite particles, fused silica, magnesia and alumina as main starting material.Effects of addition of 2% -10% SiC on the thermal expansion, flexural strength and thermal shock resistance were studied, and the fracture surface morphology was observed with Scanning Electron Microscope (SEM). The results showed that the multiphase ceramics materials thermal expansion coefficient and flexural strength had little change. The thermal shock resistance of cordierite-mullite multiphase ceramics material varied as increasing-decreasing with the increase of SiC content, when the content of SiC was as high as 4%, the highest conservation rate of the flexural strength after 1100℃-water(3 times) was 72.08%, and the thermal shock resistance of cordierite-mullite multiphase ceramics material was superior.
