Aluminum Oxide Polishing Powder from China
Aluminum Oxide Polishing Powder from China is an alumina raw material produced from high-purity industrial aluminum oxide powder through different temperature calcination processes. By calcination, the physical structure of alumina will change, and alumina will be transformed into α – Al2O3 with superior properties. Calcined alumina is widely used in fields such as grinding, lithium batteries, electronic ceramics, aerospace, thermal conductive materials, refractory materials, etc.
Characteristics of Aluminum Oxide Polishing Powder from China:
- Uniform particle size distribution, strong cutting force, and good brightness..
- Good fluidity, no damage during grinding.
- Moderate hardness, minimal scratches without damaging the primer.
