Medical Definition of ALUMINA. : an oxide of aluminum Al2O3 that occurs native as corundum and in hydrated forms (as in bauxite) and is used in antacidsâcalled also aluminum oxide.
The purified dry ore, called alumina, is aluminium oxide-Al2O3. The alumina must be molten for electrolysis to work, since the ions are not free to move in the solid state. Unfortunately, alumina has a high melting point (2040 Â°C) and it is not practical to do electrolysis at such a high temperature.
