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.1). High temperature resistance.
2). Strong thermal shock stability
3). Resisting corrosion and stripping
4). Long working life
5). Effectively reduce probability of product's deformation, slag stripping etc defects.
Main purpose of crucible and sagger is as a container for analysis and firing of material and product applied in various industries. For example: analysis of coal, melting of the metal, analysis and firing of chemical raw materials, analysis and melting of glass, analysis and firing of rare earth materials and mineral,firing of high
temperature items such as ceramic products and melting of single-crystal raw materials.
