Alumina ceramics with excellent plasma corrosion resistance and high wear resistance

Alumina ceramics is a kind of precision ceramic material, we can effectively improve the application efficiency and actual durability of alumina ceramics by adding aluminum oxide powder into the ceramics, with good conductivity, mechanical strength and high temperature resistance, is one of the most widely used ceramics.

The important advantage of alumina ceramics is that its bending strength is quite high, and the degree of hot pressing is much higher than other materials of the same type. In terms of Mohs hardness is invincible, exclusive advantage, coupled with a very good wear resistance, so it is often used to make tools, ceramic bearings...etc. Ceramic tools and industrial valves are the current preferred choice for alumina ceramic applications.

2. Chemical field

Alumina materials also have a broad future in the chemical industry, whether it is chemical packing balls or corrosion resistant coatings, the inorganic polymer materials used must be high temperature resistance and good thermal stability. Alumina ceramics will not be compressed under high strength and high pressure, can resist the erosion of organic solvents and chemical raw materials, can be used repeatedly, and meet the conditions of chemical work.

3. Electronic-electricity aspect

Alumina ceramics also play a significant role in electronic-electricity aspect , and various ceramic substrates, ceramic films, transparent ceramics and insulating devices are inseparable from alumina ceramics. In the major electronic business field, transparent ceramics is an important direction of the current research and application of new technology, not only has a high range of light transmission, high thermal conductivity, low conductivity, wear resistance and a series of advantages are more popular.

4. Building hygiene

The application of alumina ceramic lining brick and microcrystalline wear-resistant alumina spherical stone for ball mill has been very popular, and the application of alumina ceramic roller, alumina ceramic filter tube and various alumina and alumina combined with other refractory materials can be seen everywhere.

5. Other aspects

Various composite and modified alumina ceramics such as carbon fiber reinforced alumina ceramics, zirconia reinforced alumina ceramics and other toughened alumina ceramics are increasingly used in high-tech fields; Alumina ceramic abrasives and advanced polishing pastes are playing a more profound role in the machinery and jewelry processing industry; In addition, the alumina ceramic grinding medium has superior performance in the grinding and processing of raw materials in the coating and pharmaceutical industries.
