Aluminum Oxide Usage and Synthesis:

Aluminum Oxide is a stable oxide of aluminum with the chemical formula Al2O3, also known as alumina in mining, pottery and materials science. It is a white solid insoluble in water It is odorless, tasteless, extremely hard, and easily absorbs moisture without dampness (burned does not absorb moisture). Compared with other materials, alumina has many unique and excellent properties, such as high melting point (2015 ℃), high room temperature and high temperature strength, high chemical stability and contact dielectric properties, good electrical insulation, high hardness ( Mohs hardness 9), good wear resistance and low cost.

Pharmacokinetics of Aluminum Oxide:

Aluminum Oxide is an amphoteric oxide, soluble in inorganic acids and alkaline solutions, almost insoluble in water and non-polar organic solvents; relative density (d204) 4.0 ; melting point 2050℃. Alumina contains the elements aluminum and oxygen. If the bauxite raw material is chemically treated to remove the oxides of silicon, iron, titanium, etc. and the product made is Very high alumina raw materials, Al2O3 content is generally above 99%. The mineral phase is composed of 40% to 76% γ- Al2O3 and 24% to 60% α- Al2O3. γ- Al2O3 can be transformed into α- Al2O3 at 950-1200°C, while significant volume shrinkage occurs.

Clinical Application of Aluminum Oxide:

Aluminum Oxide is commonly used as an analytical reagent, dehydration of organic solvents, adsorbent, catalyst for organic reactions, abrasive, polishing agent, raw material for smelting aluminum, and fire-resistant material. Fire-resistant materials. China is the world's largest alumina producer, with global alumina production of 56.3550 million tons in 2010 and China's alumina production of 28.950 million tons, up 20.14% year-on-year, accounting for China's alumina production reached 28,950,500 tons in 2010, an increase of 20.14%, accounting for 51.38% of the global share. It is widely used in the production of polymeric aluminum chloride, aluminum sulfate, paint pigments, concrete admixtures, etc. With China's electrolytic aluminum, ceramics, medicine, electronics, machinery and other industries, the market demand for alumina still has a large growth space, alumina production will continue to grow, in terms of quality The quality control will also be more strict.
