Mullite high-quality castable Refractory Materials Iron and steel smelting

Product introduction  

Mullite is a kind of high-quality refractory material, which is rare. Mullite is a mineral formed by aluminosilicate at high temperature. Mullite will be formed when aluminosilicate is artificially heated. The natural mullite crystal is slender needle and radial cluster. Mullite ore is used to produce high temperature refractories. It is widely used as thermal barrier coating in C / C composites. Mullite is a binary solid solution stable under atmospheric pressure in ai2o3-sio2 system. There are very few natural mullites with chemical formula of ai2o3-sio2, which are usually synthesized by sintering method or electrofusion method.
Purpose
Refractory, ceramics, metallurgy, casting, electronics and other industries have the characteristics of high temperature resistance, high strength, low thermal conductivity and remarkable energy-saving effect. They are suitable for the lining of petroleum cracking furnace, metallurgical hot blast furnace, ceramic roller kiln, tunnel kiln, electric porcelain drawer kiln, glass crucible kiln and various electric furnaces. They can directly contact the flame and be tested and used by relevant technical supervision departments, The products meet the technical indexes of similar foreign products.
