High quality white fused alumina electrically furnace with high grade aluminium oxide powder, it has higher hardness and slight lower toughness comparing with brown fused alumia. It is a kind of high grade refractory materials.
Specifications1.High al2o3 content>99.3%
2.Manufacturer with fepa, ansi, jis
3.Passed iso 9001:2000
4.High reputation in quality and price
White fused alumina in arc furnace with high grade processed alumina as raw materials. It has higher hardness and slight lower toughness comparing with brown fused alumina. It is also characterized by its high purity, ability of self-sharpening, better cutting, less heat emit, higher efficiency, acid and alkali resistance, good thermal stability. As the abrasive materials, it is suitable for grinding high-speed, high carbon steel, as loose grains, it widely used for bonded and coated abrasives, polishing, precision casting and so on.

Take metallurgy grade alumina powder and high purity limestone as raw material,fusing in a large electric arc furnace, then clinker go through fine grinding and homogenizing. Dianka cement has many advantages such as excellent early strength,broad scope of application, stable setting time, make it the first choice of refractory castable manufacturer both in domestic and abroad. Before leave the factory, Dianka cement will go through the castable test accoring to GB201-2000 standard(5% cement content),it could also be tested according to customer's demanded formula, help them use our cement properly.
