1. 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.
