Alumina is an inorganic substance with the chemical formula Al2O3.It is a high-hardness compound and is also called bauxite in mining,ceramics and materials science.It is a white solid insoluble in water,odorless,tasteless,and very hard in nature.It is easy to absorb moisture but does not deliquescence (non-hygroscopic after burning).Alumina is a typical amphoteric oxide (corundum is alpha-shaped and belongs to the most densely packed hexagonal compound.It is an inert compound,slightly soluble in acid and alkali and corrosion resistant. It is easily soluble in alkaline solutions and inorganic acid, but almost insoluble when mixed with water.

Alumina Al2O3 is suitable to be used for both wet or dry treatment. It can be used to grind the surface of any piece of workpiece. It is the most affordable abrasive. This type of synthetic abrasive, which is water chestnut and sharp, has a hardness that rivals diamond. It can also be used when iron pollution restrictions are high. This abrasive is used to do the most rough work. However, it can also make a pebble to be used to cut precise-sized pieces to obtain extremely low levels of roughness. Because of its high density and sharpness along with its rhombohedral structure it is one the fastest-cutting abrasives.
