The main chemical ingredient of cordierite is 2MgO@2Al2O3@5SiO2. This product is widely used for magnetic force floating railway engineer, building bridge, building railway, large power plant, plane depot that needs wide span. The main material is steatite, clay, alumina, feldspar, etc. It is made by normal ceramic technique, such as dry press. They can be used for loop framework, insulators of arc-resistance, element of composite materials, burnable nozzle of electrical insulators, and etc.
We have almost all specification of the ceramic products. Such as M 6, M 8, M 10, M 13, M 16, M 19, M 22 regular and penetrable etc.
