15-25% Water Absorption Corundum Mullite The Perfect Material For Harsh Industrial Environments

Corundum mullite brick is a high-alumina refractory product composed primarily of corundum and mullite crystal phases. The material's high-temperature performance can be affected by low melting point oxide impurities. Pure mullite raw material synthesized from industrial alumina powder and pure clay, bauxite, or silica should maintain minimal alkali metal oxide content.

Products using mullite aggregate offer excellent thermal shock resistance with slightly reduced corrosion resistance, while those made from corundum sand aggregate provide superior corrosion resistance with somewhat lower thermal shock resistance.

Corundum mullite ceramic is a high-performance material combining corundum and mullite phases, characterized by exceptional mechanical strength and insulation properties. Manufactured from alumina, kaolin, and specialized additives using high-temperature ceramic techniques, this material is ideal for demanding applications including high-voltage insulators, bushings, switch components, and other critical industrial devices.
