Overview of Alumina Al2O3
Alumina is an electrical insulator, which has a fairly high thermal conductivity to ceramic materials. The most common form of crystalline alumina is called corundum. Alumina can provide activated, super activated, acidic, alkaline, and neutral grades, and has flash grades, thin layer chromatography, biomass purification, decolorization, dioxin analysis, PCB removal, pyrogen removal and biotechnology wide holes form. Oxide does not conduct electricity. However, certain oxides of perovskite structures have conductivity in the cathodes of solid oxide fuel cells and oxygen generation systems. They are compounds containing at least one oxygen anion and one metal cation. They are generally insoluble in aqueous solutions (water) and are very stable, so they can be used in ceramic structures, such as clay bowls for the production of advanced electronic devices, and lightweight structural components for aerospace and electrochemical applications, such as fuel cells. Shows ionic conductivity. Metal oxides are basic acid anhydrides, so they can react with acids and strong reducing agents in redox reactions. Reactive chromatography grade alumina is used in lighting, photographic chromatography, and various chromatographic separation techniques. Alumina can usually be purchased in large quantities immediately. High purity, submicron and nanopowder forms can be considered. Alumina can also be made into granules, granules, powders, sputtering targets, tablets and nanopowders. Provide typical and customized packaging, as well as other research, technology and safety (MSDS) data. Please contact us for the above delivery time and price information.

How is alumina produced?
Alumina is produced through the bauxite process. The Bayer process is carried out in four steps. First, the bauxite is crushed, washed and dried, and then dissolved with caustic soda at high temperatures. Next, the mixture is filtered to remove impurities called "red mud" and discarded appropriately. The remaining alumina solution is transferred to a high tank called a settler. In the sedimentation tank, the hot solution begins to cool, and aluminum hydroxide seeds (very small particles) are added. Aluminum hydroxide seed crystals stimulate the precipitation of solid aluminum hydroxide crystals. The aluminum hydroxide precipitates at the bottom of the tank and is removed. Finally, all remaining caustic soda in the aluminum hydroxide is washed and heated to remove excess water. After this process, alumina (alumina) appears as a white fine powder. It looks a lot like sugar used in baking, but it is difficult to scratch the glass plate.
Application of Alumina Al2O3 Powder
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, aluminum smelting raw materials, and refractory materials.
Industries that use alumina include:
Medical industry
Due to the hardness, biological inertness, and chemical properties of alumina, it is used in hip replacement surgical prostheses, bionic implants, artificial eye substitutes, tissue reinforcement materials, crowns, abutments, bridges, and other dental implants. The material of choice for bearings. It is also used in laboratory equipment and tools such as crucibles, furnaces, and other laboratory equipment.
Military and protective equipment
The strength and lightweight properties of alumina help to strengthen body armor, such as breastplates and body 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
Alumina's high melting point and high boiling point and excellent heat resistance make it 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.
