Brown Fused Alumina
Physical And Chemical Properties
Brown Fused Alumina short for BFA, also known as brown fused aluminum oxide, brown aluminum oxide, and brown corundum.it is a product manufactured by gradual melting reduction of calcined bauxite in an electric arc furnace at high temperature
(approximately 2000 degrees Celsius). Its chemical composition consists mainly of Al2O3 (94,5-97%) and vestigial amounts of TiO2, SiO2, Fe2O3, CaO and MgO. It is characterized by good self-sharpening and high grinding ability. Brown Fused Alumina can be used in ceramic resin abrasive, sand blasting, grinding and polishing, and widely used in non-slip wear runway into a high-temperature basic plating, metallurgical and chemical industries of advanced refractory, the idea martial for sandblasting, cleaning parts, polishing and so on.
Brown Fused Alumina is characterized by good toughness, high mechanical resistance and hardness (9 in Mohs scale). The micro hardness of the material reaches about 1900kG/mm2. Specific gravity (density) equals 3,90+/-0,05 g/cm3. Bulk density depending on size equals 1,68-1,95 g/cm3. It has relatively high thermal conductivity and low thermal expansion. As regards electricity it is an insulator.
The particle size of the product according to the international standards and national standards of production, according to user requirements for processing granularity. Universal size is F4~F320, its chemical composition depending on the particle size and different.
Process of Production
Brown corundum has high purity, good crystallinity, strong liquidity, low coefficient of linear expansion and corrosion resistance. The product has not occurred in the application process, no powder, no cracking. Especially it is much higher than the traditional corundum price, make it become the best corundum aggregate refractory material and filling material.
The prominent feature is the small crystal size, impact resistance, strong self sharpening, particles are spherical particles, sharp Yuanpai corundumwithhigh purity high, dense texture, bulk density, strong self sharpening, good toughness, low content of magnetic material characteristics, which are made of abrasive grinding sharp, heating rate, grinding ratio, and is attached; made of sintered abrasive has burned deep blue color, can not afford to mesh cracks, characteristics no rust, suitable for the manufacture of ceramics, resin bonded abrasives and grinding, polishing and so on.
