Fused Zirconia Mullite
Description:
Fused Mullite is produced by fusing high purity alumina and silica together in an electric arc furnace in the proper ratios. The resulting product is characterized by its dendritic (needle-like) shape and unique thermal properties. Fused Mullite has a low coefficient of thermal expansion which results in a product with excellent thermal shock resistance and resistance to deformation under load.
Fused zirconia mullite is made by fusing certain percentage of high purity aluminum oxide and zircon sand in electrical arc furnace. DRSL characters small coefficient of thermal expansion, high strength, good thermal shock resistance and strong resistance to slag. It can well improve the anti-corrosive ability of the refractory products and enhance refractories wear resistance.
