Mullite is a series of aluminum silicate minerals. It is produced with high temperature. With its high temperature resistance, high intensity and small thermal conductivity coefficient, mullite is usually for the production of high quality refractories and widely used in ceramics, metallurgy, casting,electronics and other industries.

The fused mullite is made of high purity quartz sand and industrial alumina smelted in an arc furnace. It's spiculate crystals are well developed, Low carbon residue, high thermal shock stability and low creep value at high temperature . It is a high quality raw material for the preparation of mullite products such as glass kiln lining bricks, non-alkali glass sedimentation chamber mullite bricks, blast furnace hot blast furnace bricks, blast furnace low creep si-linite bricks and so on.
