Quartz ceramic is a new type high purity and high temperature quartz material. It keeps the good characteristic of quartz glass and is made through advanced ceramic process.The raw material is fused silica or quartz glass.Quartz ceramic features low thermal conductivity,low expansioncoefficience,high temperature resistance and good thermal shock resistance.

It has the unique characteristic that its strength increases greatly with the rise of temperature below 1100 ºC.Its strength increases by 33% at a rise of temperature from room temperature to 1100 ºC. Owing to its outstanding characteristics,this material has been used in a varity of wide application in Metallurgy, Electrical Engineering, Float Glass,Glass Processing, Aero Space,Precision Platform,Crucible for Polycrystalline silicon melting and Container fro torch and kiln jewelry casting.
