1. High temperature resistance.
2. Good thermal insulation.
3. Professional manufacturer.
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.
Characteristic:
1. High temperature resistance.
2. Low thermal conductivity.
3. Good thermal insulation.
4. High strength.
5. Can direct contact with flame.
6. Good chemical stability (acid-base erosion resistance ).
7. Low bulk density (lighter than the same kind of material ,thin kiln wall, low cost ) .
