The removal of 8, electronic parts, core flash, eliminate processing White corundum application field White corundum abrasives are suitable for all kinds of high-end product, process or beautify processing, hardware and other products surface after sand blasting surface clean without any impurities, cleaning trouble. Fine white corundum can be used for polishing. White corundum used as additive in various products. White corundum as a solid and coated with abrasive, wet or dry, or spray sand, suitable for crystal, ultra precision grinding and polishing in electronics industry and making high-grade refractory materials, etc. White corundum is suitable for machining hardened steel, alloy steel, high speed steel, high carbon steel hardness is harder, such as tensile strength of the larger materials. White corundum used as touch media, insulator and precision casting sand, etc. White corundum used for iron artifacts to rust, dirt, scale, increasing the coating, coating adhesion; White corundum used in aluminum workpiece to scale, surface strengthening, finishing effect; White jade for the bronze artifacts to skin inferior smooth effect, glass crystal frosted plastic, engraved designs, inferior smooth effect, special fabrics such as denim fluffy effect of processing and design.
Vice-white corundum
Electrically fused from Bayer alumina ,white colour, its hardness is a little higher ,but toughness slightly lower than that of Aluminum .It is used for fabrication of bonded and coated abrasive products for the grinding of the steels with great hardness, such as high carbon steel ,allor steel, and high speed steel.Its non-abrasive uses are precision casting moulding sand ,spray coating material ,catalyat carrier ,high temperature ceramic ,and super refractory material,etc. Size Al2O3 Fe2O3 Na2O+K2O SiO2 Density Fire-Resistance Bulk Density Volume Density % % % % g/cm3 ¡ãC g/cm3 g/cm3 Grain 99 0.05 0.4 0.06 3.96 1850 1.5-1.95 3.6 Fine 98.5 0.07 0.4 0.08 3.94 1850 1.4-1.8 3.5 Micropowder 98 0.07 0.4 0.08 3.94 1850 1.4-1.8 3.5. 25 kg / bag/50kg/bag/ton bag.

Flint clay is a representive of Chinese refractory clay. Normally, flint clay means CALCINED FLINT CLAY, it is calcined clay ore. Its Al2O3 content is about 44%, Fe2O3 less than 2%, with stable compound and dense structure,fracture surface likes broken shells. Flint clay has no fixed compound. It is like Kaolin clay (Al2O3/3SiO2=0.85), besides some free quartz, it also has very few ferro and alkalis mineral. Common color include: pure white, light gray, light tea-yellow, some are brown. Flint clay has refractoriness and sinterability. This compound of many aluminum silicate , main component is Al2O3 and SiO2. Oxide impurities will flux the material, lower its refractoriness. Lower the Na2O+K2O content, higher the refractoriness. As Al2O3/3SiO2 ratio near theoretical value(A/S= 0.85), flint clay is purer, refractoriness is higher, and its sinterablity is better .Top grade fint clay can reach 1750 refractoriness, water absorbtion less than 5%, bulk density bigger than 2.55g/cm3.
