Al2O3 powder preparation and applications

What is Al2O3 powder?
Al2O3 is a kind of inorganic, chemical type Al2O3, is a high hardness compound, the melting point of 2054℃, the boiling point of 2980℃, can be ionized at the high-temperature ionic crystal, often used in the manufacture of refractory materials.
Industrial Al2O3 is prepared by bauxite (Al2O3·3H2O) and bauxite, for high purity Al2O3, generally prepared by chemical methods. 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 a high temperature above 1300℃.

Al2O3 powder making and application
If we want to reduce Al2O3 consumption in the production process, then we must pay attention to the following skills and methods: control the particle size of Al2O3 should not be too fine, it is best to sand Al2O3, feeding anode sealing material to reduce flying, processing should close the window; When changing the anode, the material on the old pole should be cleaned up, and the Al2O3 on the residual pole should be cleaned up; Good control of precipitation, to prevent excessive precipitation and precipitation hardening; If you use clip in the production process, it is best to choose strong acid and alkali resistance PP plastic clip, avoid clip corrosion oxidation caused by pollution.
The product can be used as the defluorination agent of high fluorine drinking water (defluorination capacity), defluorination agent of circulating alkanes in alkylbenzene production, deacidification regenerating agent of transformer oil, and gas drying agent for oxygen industry, textile industry, and electronic industry. Automatic instrument wind drying and in chemical fertilizer, petrochemical drying industry as a desiccant, purifier (dew point up to 40 degrees), in the air separation industry pressure swing adsorption dew point up to 55 degrees. It is an efficient desiccant for micro water depth drying. Very suitable for heat-free regeneration devices.
Al2O3 powder remain functions
Ruby, the sapphire main ingredient is Al2O3, because of other impurities and take on a different color, sapphire contains iron oxide and titanium oxide, and blue. In the main component of bauxite, the content of Al2O3 is highest. Industrially, ferrite is purified to Al2O3 by the Bayer process and converted to aluminum by the Hall-Heroult process. Aluminum reacts with oxygen in the air to form a dense film of aluminum oxide covering the surface of aluminum exposed to the air. Aluminum is a good conductor of electricity and heat. The crystal form of Al2O3 is suitable for grinding materials and cutting tools because of its high hardness. Al2O3 powder is commonly used as a medium for chromatographic analysis. In August 2004, scientists working for 3M company in the United States developed an alloy made from aluminum and rare earth elements to make reinforced glass called Transparent Al2O3.
