Aluminium Oxide Chemical Properties,Uses,Production
Description
Aluminium Oxide is a chemical substance made up of aluminum and oxygen atoms. It has a chemical formula Al2O3. Aluminum loses three electrons in the chemical process, whereas oxygen gains two. It is frequently referred to as alumina. Alpha-Alumina, alumina, alundum, or alkoxide are other names for it. Aluminium Oxide is a white, odorless, amorphous material. Because of its multiple beneficial properties, the chemical contributes significantly to a wide range of life-extension and social welfare applications. It can also be found in bauxite.
Structure
Aluminum oxide may be found in nature as corundum, rubies, sapphires, and emeralds. It’s an alkaline earth compound that interacts with both acids and bases. It appears white and exists as a solid. This molecule is most commonly found in crystalline form, known as -aluminum oxide or corundum. The most common form of crystalline aluminium oxide is known as corundum, which is the thermodynamically stable form. The oxygen ions form a nearly hexagonal close-packed structure, with the aluminium ions filling two-thirds of the octahedral interstices.
