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.
Aluminum oxide, also called alumina, is used in engineering ceramics. Itâs hard and wear-resistant, resists attacks by both acid and alkali substances, has high strength and stiffness, and has good thermal conductivity, which makes it valuable in manufacturing a variety of different ceramic products.etallic aluminum is reactive with oxygen, which could cause corrosion to build up. However, when aluminum bonds with oxygen to form aluminum oxide, it creates a thin coating that protects it from oxidation. This keeps the aluminum from corroding and losing strength.
