Corundum Mullite Brick Corundum-mullite Bricks Used in Glass Furnaces

Corundum Mullite Brick Description

Corundum mullite bricks are made by burning bauxite or other materials with high AL2O3 content. Her refractoriness is usually higher than 1770°C. Because of its high refractoriness under load, corundum bricks are ideal materials for various industrial furnaces.

Corundum Mullite Brick Features

Corundum-mullite combines the high strength of corundum with the thermal shock resistance of mullite, making it an ideal refractory material for high-temperature and wear-resistant applications.

(1)High temperature resistance,
(2)High strength,high compression resistance,
(3)Excellent thermal shock resistance,
(4)High bulk density, good thermal conductivity,
(5)Good wear resistance and acid,alkali corrosion resistance.
