What is aluminum oxide? Aluminum oxide is an inorganic substance, a high hardness compound with a melting point of 2054℃ and a boiling point of 2980℃, ionized at high temperatures and often used to manufacture refractory materials. Aluminium oxide needs to be sealed for dry storage. Aluminum oxide contains elemental aluminum and oxygen. If the bauxite raw materials are after chemical treatment, remove silicon, iron, titanium, and other oxides and make the product a high purity of aluminum oxide raw materials, Al2O3 content is generally above 99%. Aluminum oxide is a white solid insoluble in water, odorless, tasteless, and easy to absorb moisture and not moisture solution (burned without moisture absorption). Aluminum oxide is a typical amphoteric oxide (corundum is α -shaped and belongs to the densest accumulation, is an inert compound, slightly soluble in acid and alkali corrosion resistance), can be soluble in inorganic acid and alkaline solutions, almost insoluble in water and nonpolar organic solvents.
Main uses of aluminum oxide Aluminum oxide is the main component of aluminum ore, which can be used as an analytical reagent, organic solvent dehydration, adsorbent, organic reaction catalyst, abrasive, polishing agent, the raw material of aluminum smelting, refractory material, etc. In addition, aluminum oxide can also be used as a high fluoride remover oxygen industry, textile industry, electronic industry, gas drying, as the main component of ruby and sapphire, and cutting tool and grinding material; aluminum oxide powder can be a a used as a medium for color layer analysis; aluminum oxide film can prevent aluminum oxidation, can be used as a protective layer; aluminum oxide is not easy to corrosion in air, pure metal aluminum is easy to react with oxygen in the air, forming a thin layer of aluminum oxide film to cover the aluminum surface exposed to air. This aluminum oxide film prevents the aluminum from further oxidizing. The thickness and properties of the oxide film can be strengthened by anode treatment (anode corrosion). Price of aluminum oxide The different price of aluminum oxide purity is also different. The market price of aluminum oxide is in the process of dynamic change.
