What are the applications of alumina ceramics

Alumina Ceramic

2. In terms of electronics and power, there are various Alumina ceramic base plates, substrates, ceramic membranes, transparent ceramics, and various Alumina ceramic electrical insulating ceramic parts, electronic materials, and magnetic materials. Among them, Alumina ceramic film and The research and application of coating are more.

3. In medicine, Al2O3 is more used in the manufacture of artificial bones, artificial joints, artificial teeth and so on. Alumina ceramics have excellent biocompatibility, biological inertness, physical and chemical stability, high strength and high wear resistance, and are ideal materials for the preparation of artificial bones and artificial joints. However, it has the same shortcomings as other ceramic materials, such as high brittleness, low fracture toughness, high machining technology difficulty, and complex technology, so further research and application are needed.

4. In terms of building and sanitary ceramics, Al2O3 products can be seen everywhere, such as Alumina ceramic lining bricks, grinding media, rollers, ceramic protection tubes, and Al2O3 refractory materials. Among them, Al2O3 ball milling media is widely used. In the past, the ball milling media for building and sanitary ceramics were basically natural balls such as flint and pebbles. With the reduction of these high-quality natural ball resources, and their high wear rate and low efficiency, Al2O3 ball milling media has been increasingly used. Used by many ceramic manufacturers. At present, ball milling media mainly include Al2O3, SiC, ZrO2, Si3N and so on. Al2O3 ball milling media has the characteristics of suitable hardness, moderate density, wear resistance, corrosion resistance and low price. Therefore, most of the raw materials for building and sanitary ceramics are processed with Al2O3 ball milling media.

The above introductions are common, and there are many, many applications. In terms of heat insulation and temperature resistance, Alumina ceramics are currently more researched in new materials. In addition to the above applications, it is also widely used in other high-tech fields, such as aerospace, high-temperature industrial furnaces, composite reinforcement and other fields.
