Calcined alumina is mainly used as an abrasive to make cutting and grinding tools such as sandpaper, grinding wheels, and cutting discs. It is widely used in the grinding industry due to its excellent mechanical properties, high hardness and wear resistance, and has become a popular choice among industrial users.
However, its uses in the grinding industry are not limited to abrasives. Calcined alumina is also used as a filler, which is added to the grinding wheels to improve their mechanical strength. These wheels are then used for precision grinding applications, including surface grinding, external and internal threading, and gear making.
Grinding applications require cutting and grinding tools that can withstand high temperatures and friction. Calcined alumina's high thermal stability, combined with its excellent mechanical properties, makes it an ideal material for manufacturing these tools. Moreover, it also helps reduce the surface roughness of machined parts, improving their surface finish and enhancing their functionality.
Calcined alumina is also used in lapping and polishing applications, where it is used as a fine abrasive to produce a high-quality surface finish on a range of materials. The product's high chemical purity makes it an excellent choice for polishing substrates that require high surface finish quality, such as semiconductors and optics.
The product's mechanical properties make it an ideal choice for manufacturing ceramic grinding media used in the mining industry. These grinding media are used to grind and crush mined ores, helping to extract metals more efficiently. The quality of the resulting ore concentrates is improved, leading to higher profits for mining companies.
Furthermore, calcined alumina is also increasingly being used in 3D printing technology for designing and manufacturing metal parts. It is used as a binder in the manufacturing process, which is then burned out, leaving behind a dense, high-quality metal part.
