What is Aluminum Oxide?
Aluminum oxide is a kind of inorganic, chemical formula Al2O3. It is a compound of high hardness, melting point of 2054℃, the boiling point of 2980℃, ionizable at high-temperature ionic crystals, commonly used in the manufacture of refractory materials. Industrial alumina is prepared from bauxite (Al2O3·3H2O) and diaspore. Al2O3 with high purity requirements is generally prepared by chemical method. There are many homogenous crystals of Al2O3, known to have more than 10 kinds, mainly have 3 kinds of crystal, that is α-Al2O3, β-Al2O3, γ-Al2O3. Among them, different structures and properties are also different, and almost completely converted to α-Al2O3 at high-temperature above 1300℃.

Application of Aluminium oxide:
Most of the alumina produced is used to form aluminum metal. Oxygen usually reacts with metallic aluminum to catalyze corrosion. However, when combined with oxygen to form alumina, it forms a protective coating and prevents further oxidation. This increases the strength and makes the material less prone to deterioration. Alumina is mainly used as analytical reagents, dehydration of organic solvents, adsorbents, organic reaction catalysts, abrasives, polishing agents, raw materials for smelting aluminum, and refractory materials.
Industries that use alumina include:
Medical industry
Due to the hardness, biological inertness, and chemical properties of alumina, it is used for hip replacement surgery prostheses, bionic implants, artificial eye substitutes, tissue reinforcement materials, crowns, abutments, bridges, and other dental implants. The preferred material of the bearing. It is also used in laboratory equipment and tools such as crucibles, furnaces, and other laboratory appliances.
Military and protective equipment
The strength and lightweight properties of alumina help to strengthen body armor, such as breastplates and armor for cars and airplanes, which is its largest market. Alumina is also used to synthesize sapphire bulletproof windows and bulletproof systems.
Electrical and electronic industry
Its high melting point and high boiling point, as well as its excellent heat resistance, make alumina an ideal material for high-temperature furnace insulators and electrical insulators. Alumina film is also a vital component in the microchip industry. Some of its other uses include spark plug insulators, micro-electric substrates, and insulating heat sinks.
Performance of Aluminum Oxide：
The chemical formula of Aluminum oxide is Al2O3. Alumina is a white solid insoluble in water. It is odorless, tasteless, very hard, easy to absorb moisture, and not deliquescent (burned not hygroscopic). Alumina is a typical amphoteric oxide (corundum is α form and belongs to the densest hexagonal accumulation. It 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. It is a high hardness compound with a melting point of 2054°C and a boiling point of 2980°C. It is an ionic crystal that can ionize at high temperatures and is commonly used to make refractories.
