Detailed Description

Product Description White fused alumina sand 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. Physical properties: Density: 3.9g/cm³ True Density: 3.85g/cm³ Bulk Density: 1.75~1.95g/cm³ Fire - resistant Temperature: 1850°C Melting Point: 2250 °C Mohs Hardness: 9.0 Chemical Composition Al2O3 99.5% MIN Fe2O3 0.04% MAX Na2O 0.3% MAX SIO2 0.06% MAX
