CORDIERITE
Cordierite
Cordierite chooses the fine quality kaolin, aluminium oxide and talc as the main raw material,and is sintered at high temperature. It’s featured with low thermal expansion coefficient,good thermal shock resistance. Wide range of products with good thermal shock resistance can be made by this material such as ceramic kiln furniture , honeycomb ceramics, burner ,burner block, etc.

Mullite 30 (M30)
The M30 takes clay with low alumina content as starting raw material , after the multilevel homogenizing , it is sintered at high temperature. It’s mainly composed of mullite phase and high-silica glass phase , which is featured with good thermal shock resistance and good chemical corrosion resistance.
It is the ideal material for manufacturing fire-proof coating, low melting glazes, honeycomb ceramics, high-grade sanitary ware mould, precision casting mould and acid-resistant or alkali-resistant refractories.
