Specifications

1.High purity;
2.High mechanical strength;
3.Low thermal conductivity;
4.Good stability

The alumina bubble brick used the alumina hollow ball as the main raw material, high-performance powder as additives, and organic material from the temporary binding agent .After mixing, drying, forming, and firing at high temperature shuttle kiln made. 

 

The bubble alumina brick are mainly used for lining of high temperature furnace and industry ceramic, electrical ceramic, petrochemical and metallurgical industries, as well as the insulation material for super high temperature furnace.
