Introduction white corundum:  The raw material of white corundum is AL2O3. The production process is that after the alumina is smelted into a block in a high temperature furnace by a high temperature, it is broken into small pieces by a jaw crusher, and then crushed by a ball mill for secondary crushing, magnetically removed and then sieved into various models. The micropowder needs to be pickled and removed. White corundum has high purity, good self-sharpness, low calorific value, strong grinding ability, and good corrosion resistance. It has higher hardness than brown corundum, but it has no toughness of brown corundum.  White corundum characteristics:   1. High alumina content and high hardness 2. self-sharpening, acid and alkali corrosion resistance 3. high temperature resistance, stable thermal performance, 4. Strong grinding ability, low heat generation and high efficiency. Chemical Composition AL2O3 99.2-99.7; Fe2O3 0.03-0.1; Na2O 0.23-0.32; SiO2 0.03 Main Physical Properties Mohs hardness:9 Bulk density:1.75-1.95g/cm3 Real density:3.95 Melting point:2250 Application 1.
