【Abstract】 Thermal shock resistance of SiO 2 AlN composites were investigated. The teheoretical analysis of thermal shock resistance of SiO 2 AlN composites was conducted. The results showed that the critical temperature difference was estimated to be about 600°C. The optimized mechanical properties and thermal properties will be conducive to the enhanced thermal shock resistance.更多还原
