A Look at the Applications of High Purity Alumina- Artificial sapphire
Haiwei High Purity Alumina is a series of ultra-high-purity alumina powder produced by direct hydrolysis. The purity can be as high as 99.998%. This series of products have stable quality and can be used in the production of artificial sapphire, wear-resistant and heat-conducting filler, polishing materials, super ceramics (bioceramics, electronic ceramics, etc.), wear-resistant coatings, catalyst carrier, and many other fields.

What Is Alumina

Alumina is one of the most abundant minerals in the earth’s crust, with a molecular formula of Al2O3. It’s a compound of aluminum and oxygen that has an atomic weight of 26.9897. It’s also chemically inert, which means it doesn’t react to other chemicals.

Alumina is found in abundance on earth because it can be formed by a number of natural processes, including weathering of rocks containing aluminum oxide and iron oxide, burning coal or wood with insufficient air supply (producing silica (SiO2) and alumina), or hydrothermal alteration near hot magma chambers.

Applications of High Purity Alumina
If you’re not a scientist, you might be wondering how Alumina is used. We’ll take a look at some of the applications of Haiwei High Purity Alumina .
-High purity alumina powder can be used in the production of artificial sapphire, wear-resistant and heat-conducting filler, polishing materials, super ceramics (bioceramics, electronic ceramics, etc.), wear-resistant coatings, and many other fields.
-It’s widely used in the production of artificial sapphire for its high hardness and chemical stability.
-High purity alumina powder can also be used as a phosphate remover for water purifiers to remove impurities such as calcium and magnesium from tap water because it has a very high affinity for them.

Advantages of Haiwei High Purity Alumina
The high purity grade of Haiwei High Purity Alumina can be used as a catalyst carrier in the refining process for cobalt, nickel, and tungsten. The alumina powder is also suitable for the production of artificial sapphire, wear-resistant and heat-conducting filler, polishing materials.
Alumina powder can produce white or transparent artificial sapphires with good hardness, light transmittance (mineral). Artificial sapphires are mainly used as plate windows, watch and clock inserts, decorative materials, etc. Meanwhile, they can also be used to produce wear-resistant and heat-conducting fillers by adding titanium dioxide or magnesium oxide. They are added to rubber products to improve the surface properties of the rubber against abrasion and cracking.
Alumina powder has good performance in polish material preparation. By adding diamond abrasive grains and solvents to the aluminized copper slurry (or another metal slurry), we can produce coatings with excellent scratch resistance that are resistant to thermal aging at high temperatures.
Haiwei Alumina is also suitable for use in electronic ceramics (laser mirror) production because of its special chemical properties such as alkali resistance, acid resistance, radiation resistance, etc.

Artificial sapphire
One of the main uses of High Purity Alumina is to produce artificial sapphire. The alumina powder can be mixed with crystal particles and heated at high temperatures to form a liquid, which is then cooled. This process creates an artificial sapphire that’s excellent for high-temperature heat resistance, flexible, strong, and corrosion-resistant.
The production process for artificial sapphire starts by mixing the alumina powder with other materials like crystal or silicon carbide powder. These materials are heated until they liquefy and can be poured out from a mold. After cooling and solidifying, this new material becomes an artificial sapphire that has the qualities of being very resistant to high temperatures, flexible, strong, and corrosion-resistant.
Athletes who want a more durable watch often choose one made of synthetic sapphire because it’s a lot harder than glass; it isn’t scratched as easily and can withstand higher amounts of pressure when it comes into contact with other surfaces.
This material is also used in industry when there are components that need to be exposed to extreme heat such as in automobiles, furnaces, and kilns.

Conclusion
Haiwei’s high purity alumina is a type of alumina that is suitable for a variety of industrial applications and has many advantages over other types of alumina. Artificial sapphire is another application of high purity alumina.
