Product Description

Product Description

aluminum oxide powder

aluminum oxide powder, also known as calcined alumina, is a highly versatile and widely used material in various industries due to its exceptional physical and chemical properties. This white, crystalline powder is derived from bauxite ore through the Bayer process and subsequently refined to achieve high purity levels. Alumina powder is utilized in a range of applications, from industrial manufacturing to advanced technological fields, due to its high hardness, thermal stability, and electrical insulation properties.
