The eight application fields of zirconia ceramics in modern life
一、Mobile phones and other 3C electronic fields
The non-signal shielding of zirconia ceramics is resistant to falling, abrasion, and folding. At the same time, the appearance is as gentle as jade, and the hand feels good. It is widely used in 3C electronic fields such as mobile phones. Mainly used as mobile phone backplane and other mobile phone structural parts.
2. Smart wearable field
Compared with metal, zirconia ceramics have better wear resistance, smooth surface, good texture, and no oxidation. Famous Swiss brands such as "Radar", Apple and Chanel have launched high-end ceramic watches.
3. Optical communication field
Ceramic ferrules and sleeves are widely used in optical fiber connector connectors. The ceramic ferrule made of high-strength and high-toughness ceramics can not only meet the requirements of high precision, but also has a long service life and very low insertion loss and return loss.
4. Biomedical field
Due to its high strength, high toughness, corrosion resistance, abrasion resistance and good biocompatibility, zirconia ceramic materials are most commonly used in the biomedical field as dental restoration materials and surgical tools.
Five, the automotive field
The thermal conductivity of zirconia ceramics is small, and the thermal expansion coefficient is relatively large, so the parts made of it into the engine combustion chamber have good heat insulation, and at the same time, the thermal expansion is closer to metal materials. It can be used as cylinder head bottom plate, cylinder lining, piston crown, valve seat ring, etc. However, due to the harsh working conditions of the engine, the strength of ceramic components changes greatly at high temperatures, so there is still a long way to go before commercial applications.
6. Jewelry field
High-precision ceramics and precious metal alloy powder are mixed and fired, and after several precise and strict processes and multiple machine polishing, they are finally integrated into the jewelry design. This ceramic is not only lightweight and wear-resistant, but also has anti-sensitivity properties and is comfortable to wear. It is one of the most fashionable jewelry materials at the moment, and is favored by major jewelry brands.
Seven, areas of daily life
Ceramics is the inheritance of Chinese culture for thousands of years. In addition to the above applications, ceramics are still everywhere in our daily lives. Ceramic has the characteristics of high temperature resistance, corrosion resistance, oxidation resistance, high strength, abrasion resistance, and natural antibacterial properties. It can be used as porcelain bowl spoons, vases, ceramic knives, etc.
8. Other fields
Zirconium oxide ceramics have good mechanical properties, wear resistance and corrosion resistance, and can be used as ceramic bearings or made into ceramic tools. At the same time, zirconia ceramics are weakly acidic oxides, which can resist corrosion by calculation or neutral slag (but will be corroded by alkaline slag), and can be made into refractory crucibles for metallurgy. The characteristics of high strength, high toughness, and corrosion resistance also make zirconia ceramics have certain applications in the fields of petroleum, chemical industry, machinery, and aviation.
