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

Properties: white solid insoluble in water, odorless, tasteless, extremely hard, easy to absorb moisture without deliquination (burned without hygroscopic). Alumina is a typical amphoteric oxide (corundum is α-shaped and belongs to the most dense hexagonal packing, is an inert compound, slightly soluble in acid and alkali corrosion resistance , soluble in inorganic acid and alkaline solutions, almost insoluble in water and non-polar organic solvents;

Storage: Keep sealed and dry.

Uses: Used as analytical reagent, dehydration of organic solvent, adsorbent, organic reaction catalyst, abrasive, polishing agent, raw material for smelting aluminum, refractory
