high grade M70 M60 fused mullite used sintered mullite

"Jun" brand fused mullite is mainly made of industrial alumina powder and high-quality quartz sand, and smelted by a large-scale high-temperature arc furnace. Fused mullite is the only binary compound in the aluminum-silicon binary system that is stable at atmospheric pressure and is a high-quality refractory material. The color is gray white, needle-like crystals, and high bending strength. It has the characteristics of uniform expansion, good thermal shock resistance, high load softening point, low temperature, high rigidity value, high hardness, and good resistance to chemical corrosion. With its excellent thermal shock resistance and wear resistance, it is widely used in glass kiln lining bricks, alkali-free glass sedimentation mullite bricks, large-scale smelting blast furnace hot blast stove bricks, blast furnace low creeping sillimanite bricks, ceramics Kilns, squats, slats, petrochemicals and other industries. It is the raw material for high-grade refractory materials.

Mullite is the main raw material for mullite bricks.
