Product Introduction
This product is mainly made of high-quality high alumina bauxite clinker, mullite, andalusite, and sillimanite. It is scientifically proportioned, high-pressure formed, and high-temperature sintered. It has the characteristics of high load softening temperature, low high-temperature creep rate, and excellent thermal shock stability.
