What aluminium Trioxide can be use?

Answer 1

Aluminum(III) oxide Al2O3 or Alimuna (or alumina) is used as follows:

• Being fairly chemically inert and white, alumina is a favored filler for plastics. Alimuna is a common ingredient in sunscreen and is sometimes present in cosmetics such as blush, lipstick, and nail polish.
• Alumina is widely used to remove water from gas streams.
• Aluminum oxide is used for its hardness and strength. It is widely used as an abrasive, including as a much less expensive substitute for industrial diamond. Many types of sandpaper use aluminum oxide crystals. In addition, its low heat retention and low specific heat make it widely used in grinding operations, particularly cutoff tools

• Aluminum oxide flakes are base material for effect pigments. These pigments are widely used for decorative applications e.g. in the automotive or cosmetic industry.

Answer 2

Aluminum trioxide, also known as alumina, is commonly used as an abrasive material in processes like sandpaper and grinding wheels. It is also used in the production of ceramics, refractory materials, and as a catalyst in chemical reactions. Additionally, aluminum trioxide is used in the manufacturing of high-strength aluminum alloys.
