OEM China White Aluminum Oxide Powder For Polishing - Abrasive Material White Fused Alumina Grits – Xinli

White fused alumina is alumina powder as raw material, regularly above 2000 ℃ high temperature smelting electric arc furnace, after smashing plastic, magnetic separation to iron, screen is divided into a variety of particle size, dense texture, high hardness, granular form Angle hardness is higher than brown fused alumina is slightly, slightly lower toughness, strong cutting force and chemical stability is good, has the very good insulation.

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
