Monocrystalline alumina is also known as single crystal fused alumina, with bauxite, coal, scrap iron and pyrite as the main raw materials, in the process of smelting in the electric furnace with the temperature of 2050℃, breaking, hydrolysis and manufacturing. Each particle is a single crystal, giving many sharp strong edges. It is a kind of high-grade grinding material, which is used to produce the high grade cutting and grinding tools.
Monocrystalline Alumina is suitable for the material grinding of high hardness, high toughness such as high vanadium high speed steel, austenitic stainless steel, heat-resistant alloy steel, titanium alloy steel, especially for the grinding and processing of dry mill and easily burned workpiece.
Here is a typical specification of Monocrystalline Alumina:
• Base mineral: alpha-Al2O3
• Crystal size(um): monocrystalline
• True density(g/cm3): > 3.95
• Bulk density(g/cm3): 1.85 ~ 1.91
• Knoop hardness(kg/mm2): 2200 ~ 2400
• Toughness (single grain crushing strength)(kg): 1.20
