Activated Alumina Powder: It is also known as alumina or activated alumina, is a compound used primarily in the production of aluminum, one of the metals important in advancing a low-carbon economy and industry as a whole. Activated alumina powder is made from bauxite, the main ore of aluminum. Bauxite consists of a mixture of alumina trihydrate, boehmite, iron oxide, iron hydroxide, quartz and clay minerals. Alumina is extracted by the Bayer process, in which the chemical component Al2O3 (activated alumina powder) is distilled from the bauxite mixture.
The unique properties that make alumina ideal for aluminum production also make it valuable for many other applications, especially those requiring hardness and abrasion resistance or other forms of chemical wear. Activated alumina powders are also ideal for products requiring corrosion and abrasion resistance, as well as products requiring high thermal conductivity, such as electrical insulation and thermal insulation applications.

Properties of Activated Alumina Powder: Alumina has a relatively high melting and boiling point, as well as a very high level of hardness. Its mechanical and compressive strengths are higher than many comparative materials, and its resistivity and thermal conductivity make alumina ideal for many electrical products.

What are the uses of activated alumina powder?
Aluminum oxide is an important material for industrial applications as well as other areas of science, engineering and technology. It is used in everything from building materials and abrasives to biomedical devices and chemical catalysts. Activated alumina powder is almost as versatile as aluminum itself.
