WFA serial product is a high-grade abrasive raw material. It's made by melting high-quality industrial alumina powder in an electric tilting furnace at a high temperature above 2200℃. After cooling and grinding, as well as one process after another, the finished product is ready. The main crystalline phase of this product is α- Al2O3, and white in color.
used Mullite is manufactured by fusing a mixture of high purity Bayer Alumina and pure Quartz in a tilting type arc furnace at a temperature around 2000 deg C. Controlled cooling of the molten mass ensures a high degree of mullitization characterized by well-defined columnar crystals. Fused Mullite is one of the main raw materials used by the refractory industry for applications requiring thermal shock resistance and corrosion resistance. The YUFA Group also produces micro sodium mullite with a sodium oxide content of less than 0.1%, and the primary crystal phase is mullite. Due to the reduced sodium oxide content of micro-sodium mullite, its refractoriness, volume density, flexural strength, compressive strength, true density, hardness, etc. are significantly improved compared to Common mullite. Micro-sodium mullite is mainly used in mullite firing plates, precision casting, high-quality refractory materials and other fields. Our company can produce various specifications of granules and fine powder according to customer needs.

It is also the main raw material for various corundum products such as corundum bricks, corundum and mullite corundum saggers, corundum porous plugs for refining, integral spray guns and composite nozzles, and high-temperature industrial furnace lining materials.
Fused dense corundum is a new type of high-purity refractory materials formed by using high-purity alumina and reducing agent in a certain ratio, smelting in electric arc furnace and cooled. The main crystal phase is α-Al2O3 and color is light gray.
Fused Alumina Magnesia Spinel is a new type of high-purity synthetic refractory material made from alumina and high-purity light-burned magnesia as the main raw materials in an electric tilting furnace after being melted at a high temperature of more than 2000 and then cooled.
Monocrystalline fused alumina, melting at high temperature by special process, is a high-end grinding material. The abrasive particles are off-white.
