Function and application of alumina ceramics
Oct 10, 2020
Mechanical applications
Alumina ceramic sintered products can reach 270MPa, hot-pressed sintered products can reach 480MPa, because of its good anti-wear performance, so it is widely used in ceramics, manufacturing cutting tools, grinding wheels, bearings and other industries, which is in Al2O3 ceramic tools and industrial applications are the most widely.
Electronic and electrical applications
In chemical applications, alumina ceramics also have many USES, for example, alumina ceramic corrosion resistant coating and chemical filler ball, etc., among which alumina ceramic film and silicon steel grade coating research and application.
Medical applications
Alumina ceramics have good biocompatibility, bioinertia, stability, high hardness and high wear resistance, and are often used in the preparation of artificial bone and joint materials.
Application of building sanitary ceramics
In the gemstone industry, ruby, sapphire are alumina crystals containing trace impurities, and artificial gems can be used as a variety of wear-resisting components, doped sapphire can also be used as the optical activation components of the solid-state laser.
In particular, alumina ceramics have been used more and more in the fields of energy, military, machinery, electronics, medicine and other high technology by using the pervious to light, wave, laser and other functional characteristics.
Research and application of alumina ceramics in new energy field
In recent years, due to the global energy shortage and increasingly serious environmental problems, all countries are increasing investment in the layout of new energy vehicles, new energy vehicles to replace fuel vehicles has almost become an inevitable trend. In 2018, the penetration rate of China's new energy automobile industry is 3.73%, and the potential market space is huge.

Electronic and electrical applications
It is the most widely used transparent alumina ceramics and matrix in electronics, electric power, alumina ceramic substrate, floor, transparent ceramics and various alumina ceramics, ceramic parts, electronic materials, magnetic materials and so on.
Applications in chemical engineeringIn chemical applications, alumina ceramics also have many USES, for example, alumina ceramic corrosion resistant coating and chemical filler ball, etc., among which alumina ceramic film and silicon steel grade coating research and application.
Medical applications
Alumina ceramics have good biocompatibility, bioinertia, stability, high hardness and high wear resistance, and are often used in the preparation of artificial bone and joint materials.
Application of building sanitary ceramics
Alumina ball grinding medium has good hardness, moderate density, wear resistance and low price, so most of the raw materials used in the construction of sanitary ceramics are alumina ball grinding medium mechanical processing.
Other applicationsIn the gemstone industry, ruby, sapphire are alumina crystals containing trace impurities, and artificial gems can be used as a variety of wear-resisting components, doped sapphire can also be used as the optical activation components of the solid-state laser.
