Uses and synthesis of Aluminum oxide powder

Aluminum oxide powder, commonly known as alumina, chemical formula Al2O3, a refractory and insoluble in water white powder. It has a melting point of 2015°C, a boiling point of 2980°C, a relative density of 4.0, and a Mohs hardness of 8.8. Aluminum oxide CAS 1344-28-1 has different crystalline forms, with two main variants: α and γ. Aluminum oxide can be obtained by heating and dehydrating aluminium hydroxide. Aluminum oxide Raw Materials can be obtained by heating and dehydration of aluminium hydroxide.

Applications / Functions of Aluminum oxide powder

• Aluminum oxide powder is used for polishing abrasives, artificial teeth, artificial bones, magnetic tapes, picture tubes, rubies and sapphires, high-density ceramic substrates for electrical applications, etc.
• Aluminum oxide CAS 1344-28-1 is used in the manufacture of artificial gemstones, YAG laser crystals and integrated circuit substrates. Used as analytical reagent and advanced ceramic raw material for high pressure sodium lamp arc tube.
• Used in industrial high temperature furnaces such as heating furnaces for forging and even heat furnaces. Aluminum oxide Raw Materials can also be used as reinforcement with reinforcing fibres, furnace lining, electronic components (IC board, ferrite calcination furnace, etc.).
• Aluminum oxide powder used as catalyst and catalyst carrier, is the main catalyst and carrier in petroleum refining and petrochemical industry. Also used as dehumidifier for air and other gases, deacidifier for transformer oil and turbine oil.

Used as raw material for rare earth trichromatic phosphor, long afterglow phosphor, submicron/nano grinding material, etc.
