High Purity 99.9% Alumina Powder for Lapping Aluminum Oxide Polishing Fine Powder at 1.000kg Gross Weight Hardness 9 Mohs

Alumina powder is a high-purity, fine-grained material made from aluminum oxide (Al2O3) that is widely used in a variety of industrial applications. It is a white crystalline powder that is typically produced through the refining of bauxite ore.
Alumina powder has a range of desirable properties, including high hardness, chemical resistance, and electrical insulation, which make it a valuable material in many industries.
It is commonly used as a raw material for the production of ceramics, refractories, and abrasives, as well as for the manufacturing of various electronic components, such as insulators, substrates, and semiconductor components.
