With bauxite, carbon material, iron filings as raw materials, Brown Fused Alumina is restored and obtained through the melting of the brown the brownartificial corundumin the furnace above 2200 ℃, and made of a variety of particle sizes products by purifying, crystallization, sorting, crushing, magnetic separation and screening methods. With its dense texture, high hardness and the formation of spherical particles, it is suitable for the manufacture of ceramics and resin, as well as the high-Bonded Abrasives grinding, polishing, sand blasting, precision casting and so on, also can be used to manufacture high-grade refractory material.
Brown Fused Alumina has high purity, good crystalline liquidity, low coefficient of linear expansion, corrosion-resistant and other characteristics. Dozens of refractory manufacturers have proved in practice that the product has not detonate, non-powder, non-cracking characteristics in the application process.
Particle size is in accordance with international standards and can be processed as requirements. Universal size: No. F4 ~ F320, its chemical composition varies depending on grain size. Its prominent feature is the small crystal size, impact resistance and spherical particles. This product has high purity, dense texture, large bulk density, strong self-sharpening, good toughness, low level magnetic material content and other characteristics.
