Customized Mullite Ceramic Bobbin Tube Refractory Cordierite Welding Ring
Material: Cordierite-mullite ceramic
Cordierite is a magnesium alumina silicate material, which has very low linear expansion, low coefficient of thermal expansion and excellent resistance to thermal shock.Cordierite is also a ceramic used in heat shock applications that would crack and shatter most other ceramic materials.
Kiln furniture is made of cordierite because it will survive thousands of heating and cooling cycles.
Application of mullite ceramic part
The main raw materials of cordierite are clay, talc, alumina, etc. Due to its low coefficient of thermal expansion, it is generally used in harsh environments with heat shock resistance. It can be used as a coil skeleton, electric insulation material resistant to arc action, base material for composite materials, and material for burner nozzles of electric thermal insulation devices.
Advantages of cordierite ceramic board
1. It has the characteristics of acid resistance, wear resistance, high temperature resistance, anti-static, etc
2. Long term use can extend the service life of equipment by more than ten times
3. Not easily corroded, high precision, high density, high mechanical strength, strong chemical stability
4. Strong electrical insulation, insulation at room temperature, high resistivity
5. Anti magnetic, does not absorb dust, can reduce surface detachment
