White Fused Alumina

White Fused Alumina , was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase alpha-Al2O3.The white alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.As refractory: 0-1mm 1-3mm 3-5mm 5-8mm 8-12mm Al2O3≥99.55%Na2O≤0.2%CaO≤0.4% 180F 200F 320F Al2O3≥99.0%Na2O≤0.3%CaO≤0.5% As abrasives:F12-F1200 JIS240-JIS3000 White Fused Alumina can be used as consolidation & coating abrasives, wet or dry sprayed grit, suitable for ultra-precise grinding and polishing in the crystal and electronic industry and can be used to produce high-grade refractoriness. It is suitable to machine high stiffness &high tensile strength materials such as chilled steel, alloyed steel, high-speed steel, high carbon steel, etc. In addition, it can be used as catalyst, insulator, precise foundry sand, etc Chemical Compositions Grit Typical value Fine powder Typical value Al2O3 ≥99.53 99.5 ≥99.25 99 Fe2O3 ≤0.040.05 ≤0.060.08 SiO2 ≤0.040.06 ≤0.140.06 K2O+Na2O ≤0.250.3 ≤0.330.35 Apparent porosity 6.0 Bulk Density 3.60 3.62 True density 3.92 3.92 3.92 3.93 Mills:White Fused Alumina plantsBrown Fused Alumina plantsMullite plantsSales CompanyZhengzhou Haixu Abrasives Co.,LtdAbout usZhengzhou Haixu Abrasives Co., Ltd, founded in 1999,is specialized in White Fused Alumina, Brown Fused Alumina, Mullite and other related products.
