As a kind of refractory materials, white fused alumina grit is generally used for aggregate and fine powder, because it has the characteristics of high refractoriness, wear resistance, corrosion resistance, etc., and it also has the characteristics of high load temperature and high-temperature volume stability when making products. The products of white fused alumina refractories include iron making castables, corundum bricks, magnesia-alumina-carbon bricks, etc. White Fused Alumina Grit for Refractory Specifications Items Unit Index Typical Chemical Composition Al2O3 % 99.00min 99.32 SiO2 % 0.20max 0.09 Fe2O3 % 0.10max 0.03 Na2O % 0.40max 0.23 Refractoriness â?? 1850min Bulk Density g/cm3 3.50min Mohs Hardness --- 9.00min Principal Crystalline Phase --- �±-Al2O3 Refractory Grade Grain mm 0-50, 0-1, 1-3, 3-5, 5-8 Fines mesh -200, -325 Grit (F Grade and P Grade) FEPA 8, 14, 16, 20, 22,24, 30, 36, 40, 46, 60, 70, 80, 90, 100, 120, 150, 180, 220, 240 White Fused Alumina Grit for Refractory Typical Physical Properties 1.The white fused alumina grit for the refractory series has high purity. 2.White fused alumina grit has high thermal stability. 3.Stable chemicals are another white fused alumina property, With over 20 years' concentration on research and development, we have become one of the leading abrasive material suppliers in China.
