Corundum mullite sagger

Traditional refractory materials such as corundum and mullite have many advantages, such as high load softening temperature and good creep resistance. However, the thermal shock resistance of pure corundum products is not ideal due to the large thermal expansion coefficient. The thermal expansion coefficient of mullite material is significantly lower than that of corundum, which can be used as the secondary crystal phase or binding phase of the product. Therefore, corundum mullite products combine the properties of the two materials, especially the thermal shock resistance is greatly improved compared with corundum products. It is used in the pusher kiln of firing high temperature ceramic materials, and its service life is more than 100 times.
