This product is mainly used in the production of ceramic kiln furniture. It is synthesized from high-quality kaolin, alumina, and talc as primary raw materials, and produced through high-temperature calcination. It features a low coefficient of thermal expansion and excellent thermal shock resistance, and is widely applied in kiln furniture and related industries. It can also be used as an additive to improve the thermal shock resistance of refractory materials or ceramic products.
