PRODUCT DESCRIPTION：YONAI Bubble Alumina Brick
YONAI Bubble Alumina Brick is made of high purity bubble alumina as raw material and advanced micro powder as additive, organic compound material as binder and calcined at high temperature in tunnel kiln. The product will increase the thermal efficiency of the kilns and furnaces, shorten the production circle life, reduce the weight of the kilns which will save energy. Bubble alumina brick can directly contact the fire. Our product working performance is at same level with world famous ones.
Properties
