High Quality Refractory Material White Fused Alumina Grits with Free Sample
White fused alumina / White Corundum Grit is a high-grade refractory material, which made from high-quality alumina powder by melting above 2000 ℃ in the electric arc furnace and cooling, classified into different grain sizes. The white fused alumina is the main raw material for the production of unshaped and shaped refractory materials.
White fused alumina is made of high-purity low-sodium alumina powder by melting at the high temperature, cooling crystallization, and then crushing. The white fused alumina grit is under strict controlling to keep the grain size distribution and the consistent appearance.
Commonly used in ladle castables, iron runner materials, refractory gunning mix materials and other monolithic refractory products; For the shaped refractory materials, it is mainly used in the high-quality raw materials of corundum brick, corundum mullite, refining steel porous plug brick, integral spray gun, steelmaking and continuous casting industry.
It also can be used as materials for polishing, precision casting, spraying and coating, special ceramics

Advantages
0-1mm Refractory white fused alumina
1. High hardness and dense particles. Single particle roundness is good.
2. The color is pure white, no impurities, to ensure the wear-resistant layer or wear-resistant paper color and transparency.
3. Uniform distribution of particle size, single particle shape consistent, with a small amount of wear - resistant effect.
4. Chemical stability and acid, alkali no action, high temperature stability is very good.
1.Sandblasting, polishing and grinding of metal and glass.
2.Filling of the paint, wear-resistant coating, ceramic, and glaze.
3.Making of grinding wheel, sandpaper and emery cloth.
4.Production of ceramic filter membranes, ceramic tubes, ceramic plates.
5.For the use of wear-resistant floor.
6.Sandblasting of circuit boards.
7.Sandblasting of ships, aircraft engines, train tracks and outer bodies.
8.Various white fused aluminum oxide grains can be produced according to customers’ different demands.
