Using high-purity raw materials, molten mullite has the characteristics of low porosity and low impurity content, and can be processed into different particle sizes, fine powders and micropowders. Molten mullite is made of high-purity quartz sand and industrial alumina, smelted in large electric arc furnaces. The color is white, the residual carbon is low, and the needle-like crystals are well developed. With its excellent thermal shock resistance and wear resistance, it is widely used in glass kiln lining bricks, alkali-free glass precipitation tank mullite bricks, large smelting blast furnace hot blast stove bricks, ceramic kiln furniture, petrochemical and other industries. Raw materials for refractory materials. We can produce various specifications of products according to customer needs.
