Detailed Description

1.Description White Aluminium Oxide, 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. 2.Chemical composition and physical charasteristics: White Aluminium Oxide Function Model Number Main Chemical Composition (%) Al2O3 SiO2 Na2O Fe2O3 Abrasive F10-F80 99.8min 0.04max 0.22max 0.04max F90-F180 99.7min 0.04max 0.25max 0.04max F220-F240 99.55min 0.04max 0.25max 0.04max Polishing F280-F600 99.55min 0.10max 0.26max 0.05max F800-F1500 99.55min 0.14max 0.30max 0.06max F2000 99.20min 0.15max 0.32max 0.07max F2500 99.00min 0.15max 0.35max 0.08max Refractory material 0-1,1-3,3-5,5-8mm 99.60min 0.04max 0.20max 0.04max 180,200,240,280,320F 99.50min 0.05max 0.30max 0.04max Item Property Color White Bulk density 1.75-1.95g/cm3 Grain density 3.90g/cm3 Morse hardness 9 Melting point 2250°C Refractoriness 1850°C 3.Usage: F10-F240 (1)It can make the abrasive tool to grind the great hardness material, such as the high speed steel, stainless steel and high carbon steel.
