Application of mullite.
Refractory materials, ceramics, metallurgy, casting, electronics and other industries. It is suitable for the inner lining of petroleum cracking furnace, metallurgical hot blast furnace, ceramic roller kiln, tunnel kiln, electric drawer kiln, glass crucible kiln and various electric furnaces. It can directly contact the flame.
The porous material made from mullite fiber has the advantages of high porosity, light weight, low thermal conductivity, high permeability, non-brittleness, etc. And has a wide range of application prospects and in the fields of chemical industry, metallurgy, and environmental protection.
Pores in fiber porous ceramics are formed between fibers, and the contact points between the fibers are connected by binder. Therefore, the firmness of the binder bonding plays a decisive role for the full play of the excellent performance of the ceramic fiber substrate and the final performance of the product. Because the base material of the molded porous ceramic is mullite fiber, using a binder which has the same crystal phase, microstructure, and consistent thermal expansion as mullite fiber after sintering will make molded porous ceramic has better performance.
