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.
Overall, alumina powder is a versatile material that finds extensive use in a wide range of industrial applications due to its unique combination of physical and chemical properties.
