Brown fused aluminum oxide, otherwise known as Brown Fused Alumina or BFA, is produced through an electric arc furnace process. Brown fused aluminum oxide is both a hard (Mohs hardness 9) and tough material with high strength, making it an excellent abrasive grain raw material for applications such as blast media, sandpaper, grinding wheels and abrasive discs, rolls, belts and pads. Its thermal properties make it an excellent raw material for refractory applications, as well.

Garnet sand is made of garnet as raw material. It is a kind of iron-aluminum silicate with moderate hardness, high melting point and stable chemical properties. According to different products and structures, it presents different colors, such as dark red, brown red, pink and black. Widely used in optical industry, electronic industry, machinery industry, oil and gas and other industries.

 Green silicon carbide is made of petroleum coke and high quality silica as main raw materials, adding salt as additive, and smelting at high temperature in resistance furnace. Green crystal, brittle and sharp, and has a certain thermal conductivity and electrical conductivity.

Garnet sand Garnet is cubic system crystal, without cleavage, so after sandblasting, it is easy to form approximate cube particles with edges and corners. Good sandblasting effect can make the metal surface’s rust, oxide, coatings and pollutants  removed thoroughly.

Abrasive white aluminum oxide is a white abrasive made from industrial alumina powder (Al2O3) with a content of over 98% and a small amount of iron oxide and silicon oxide. It is a white abrasive which is melted at high temperature. Its hardness is slightly higher than that of brown corundum and its toughness is slightly lower. It is made by smelting and cooling above 2000 degrees in arc, grinding and shaping, removing iron by magnetic separation, and sieving into many kinds of granularity. It is compact in texture, high in hardness and sharp in shape.

White corundum was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling.After two crushing and shaping by the grinder, the iron is magnetically selected and finally sieved into different models of grains. The main chemical component of white corundum grains is AL2O3, which is white opaque and has a high Mohs hardness. The white corundum grains has the characteristics of high temperature resistance, acid and alkali corrosion resistance, strong grinding ability and stable thermal performance. It is suitable for surface beautification of glass and metal, and can also be used as raw material for sandblasting and rust removal.

Since September, with the gradual recovery of domestic demand, my country’s black silicon carbide abrasive market orders are increasing, and corporate inventories are also decreasing. Superimposed on the recent increase in the price of raw material petroleum coke and other factors, some black silicon carbide abrasive manufacturers intend to raise prices. Some people in the industry predict that the price of black silicon carbide abrasives in my country will increase by more than 5% in the coming week.
