Physical and chemical properties

Aluminum oxide (aluminium oxide), chemical formula Al2O3. It is a high hardness compound with a melting point of 2054°C and a boiling point of 2980°C. It is an ionized crystal that can be ionized at high temperature and is often used in the manufacture of refractory materials. White solid insoluble in water, odorless, tasteless, extremely hard, easy to absorb moisture but not deliquescence (burned does not absorb moisture). Amphoteric oxide, soluble in inorganic acids and alkaline solutions, almost insoluble in water and non-polar organic solvents; relative density (d204) 4.0; melting point 2050 ° C. Relative molecular mass: 101.96. CAS registration number: 1344-28 -1. Density: 3.5-3.9g/cm3


Alumina powder is often used as a medium for chromatographic analysis. ceramics. Manufacture of tempered glass. Aerospace, Automotive, Consumer Goods Processing, Foundry/Die Casting, OEM Distributors, Semiconductor Industry and many more.
