Refractory Corundum mullite Brick for Key Parts of Ceramic Tunnel Kiln

Refractory Corundum mullite Brick has uniform internal structure high compressive strength corrosion resistance heat resistance shock resistance oxidation resistance high operating temperature and low thermal conductivity.
Model Number: hongtai
Minimum Order Quantity:



Corundum mullite bricks are made from compact fused corundum, alumina powder and so on.The purity of corundum sand and the technological formula are used to meet the requirements of different corundum products. 

Properties of fused alumina mullite brick:

1. Heavy materials have good compactness, high compressive strength, corrosion resistance of various corrosive gases, good thermal shock stability, good thermal conductivity and wear resistance.

2. The material has uniform internal structure, high compressive strength, corrosion resistance, heat resistance, shock resistance, oxidation resistance, high operating temperature and low thermal conductivity.
