Product Introduction
This product is mainly made of high-quality high alumina bauxite clinker as the main raw material, added with special additives, and sintered at medium temperature. The product is mainly composed of corundum and mullite as the main crystal phases, and the special additives cause the formation of micro cracks and micro pores inside the product. It has the function of digestion and easy absorption of thermal stress, making the product have high load softening temperature, corrosion resistance, peeling resistance, and excellent thermal shock resistance.
