Corundum mullite brick: Good compactness, erosion resistant, low thermal conductivity. Used for linings of glass ceramic kilns, high temperature metallurgical equipment, cracking furnaces, CFB boilers, etc.
Corundum mullite refractory bricks are high-end refractory products. They are sintered at high temperatures in an oxidizing atmosphere, mainly using high-purity corundum and mullite as raw materials. Their unique interlaced crystal structure of corundum-mullite endows the products with excellent high - temperature stability and erosion resistance, and they are widely used in high-temperature industrial fields such as glass kilns and metallurgical equipment.
