The "JUN" brand white fused alumina using high quality aluminum oxide in the arc furnace by high temperature above 2000 ℃ melting, and then through different cooling processes to produce a high-grade refractory, abrasive basic raw materials, the main crystal phase is α-Al₂O₃, the color is white, using tipping arc furnace production, by grinding and shaping, magnetic separation, sieve into a variety of granularity.

As refractory : white fused alumina is the main raw material for the production of high-grade unshaped and shaped refractory materials, which is widely used in steel, cement, ceramics, petrochemical and other industries, it is an ideal raw material for the production of large-scale ladle castable, medium and high-grade iron runner castable, spray filler, prefabricated and other unshaped refractory materials, At the same time, it is also the main raw material for the production of corundum bricks, corundum & spinel, corundum & mullite bricks and various corundum saggar and other products.

As an abrasive: can be consolidated and coated with abrasives, wet or dry blast sand, suitable for crystal, electronic industry superfine grinding and polishing etc. It is suitable for processing materials with high hardness and tensile strength such as quenched steel, alloy steel, high-speed steel, and high carbon steel. It can also be used as touch media, nonconductor and precision casting sand. The particle size of the product is produced according to international standards and national standards, and can be processed according to the particle size required by users.
