    Aluminium oxide is an inorganic substance with the 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 ionizable ionic crystal at high temperature and is often used in the manufacture of refractory materials.

    Alumina is a stable oxide of aluminum with the chemical formula Al2O3. It is also known as bauxite in mining, ceramics and materials science.

    Molecular structure diagram Properties: White solid that is insoluble in water, odorless, tasteless, extremely hard, easy to absorb moisture without deliquescence (burned non-hygroscopic). Alumina is a typical amphoteric oxide (corundum is the densest accumulation in the hexagonal shape, it is an inert compound, slightly soluble in acid and alkali corrosion resistance), soluble in inorganic acids and alkaline solutions, almost insoluble in water and non-polar organic solvents; relative density (d204) 4.0; melting point 2050 ℃. Storage: sealed and dry. Uses: Used as analytical reagent, dehydration of organic solvents, adsorbent, organic reaction catalyst, abrasive, polishing agent, raw material for smelting aluminum, refractory material.
