Product Description
Specifications
6902 Refractory bricks,1. High temperature resistance.
2. Low thermal conductivity.
3. Good thermal insulation.
Alumina Hollow Ball Brick used the alumina hollow ball,corundum powder,and calcined powders mixed at definite proportion as raw material. After mixing, drying, forming, firing at high temperature shuttle kiln made. Physical and chemical index:
