Advantages and characteristics of cordierite mullite kiln furniture (1) High temperature resistance, high refractory temperature and high load softening temperature. (2) Chemical resistance, strong resistance to acid solution or molten slag. (3) Antioxidant. It is not easy to react with O2, H2, CO and other gases. (4) Good thermal stability, stable volume at high temperature, not easy to expand or shrink. (5) Good thermal shock resistance, resistance to rapid cold and heat, and not easy to peel off. (6) High compressive strength at room temperature, and it is not easy to wear when handling or unloading.
