Due to the high temperature of industrial kiln, the refractory materials must have the characteristics of high temperature resistance and high strength etc.

The general materials are:

cordierite, mullite, silicon carbide, silicon nitride, corundum mullite etc.



Cordierite and Mullite materials are suitable for low temperature, low working stress, high thermal shock resistance is required. Cordierite and mullite materials are often used in the shed board, column and backing plate of low temperature quick firing kiln.

Silicon carbide materials are suitable for low temperature, high working stress, high thermal conductivity and high thermal shock resistance. Silicon carbide materials are divided into oxide bonded, reaction sintered, recrystallized silicon carbide materials and nitride bonded. Oxide – bonded silicon carbide for low and middle range kiln furniture. Reaction sintered silicon carbide porosity is almost zero, has very high strength, but the use temperature should not be higher than 1350°C,  it is used for low temperature fast firing furnace, recrystallized silicon carbide has good dimensional stability and high temperature bearing capacity, it is used for temperature higher than 1350°C occasions.

Corundum Mullite material is used for high calcination temperature, such as alumina ceramics and ferrite ceramics.
