Fired alumina carbon and alumina zirconia carbon plates series

The main raw materials are tabular corundum, fused corundum, corundum, and mullite. The high temperature performance of the skateboard is improved by adding an appropriate amount of metal micro and fine powders through high temperature reaction, and an appropriate amount of boron carbide and other micro powders are added to improve the anti-oxidation performance. After forming, it adopts advanced heat treatment process, impregnation and baking to make high-performance skateboard. It has the advantages of stable volume, corrosion resistance and thermal shock resistance.
