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.
