Grinding Advanced Ceramics: All the Benefits and Applications of Alumina

13 July 2022

Manufacturers carry out tons of processes to produce their needed parts and components. One of the processes they conduct is grinding. 

Grinding is a process that is normally conducted in the mill. This process intends to generate products with very high shape accuracy and dimensional precision through the help of the grinding media. By using the right grinding media, manufacturers can expect their products to acquire their required properties.

Some grinding media are meant for filtering and polishing. Others, alternatively, are designed for deagglomeration and deburring. Some examples of grinding media are silicon carbide grinding balls, ceramic cylinders, and soda-lime glass.

A Quick Overview of Alumina

One more material that can be used as grinding media is alumina. Alumina, or aluminium oxide, is a chemical compound well-known for its role in producing aluminium and generating tons of advanced ceramic products. It can be distinguished by its white or nearly colourless crystalline appearance.

Alumina is comprised of bauxite, a type of ore that contains variable amounts of hydrous aluminium oxides. The qualities of alumina make it one of the most used materials for grinding media.

Grinding media out of alumina may come in as satellites, rods or cylinders, and beads. Most high-profile industrial milling processes use alumina media thanks to its low running costs. 

Primary Benefits of Alumina

As for advanced ceramic products, alumina can also provide tons of benefits to manufacturers and their users. One of the benefits of alumina is it has high hardness. It can also resist abrasion, chemicals, corrosion, and wear, making this material perfect for parts and products that would be exposed to damaging elements all the time. 

Alumina can likewise provide benefits to manufacturers as it has high thermal conductivity. This quality makes alumina parts and products capable of transferring and taking up heat from the surroundings. 

Best Applications of Alumina

Given the benefits and features of alumina, it can effectively be utilised in making advanced or technical ceramics. With alumina as the base material, advanced or technical ceramic products can be effectively maximised by chemical, medical, industrial, and electrical industries. These products are expected to possess enhanced wear resistance, thermal and chemical stability, and others.

Other uses and applications of alumina include the generation of industrial abrasive materials, the production of glass products, and the creation of refractory products.
