Zirconia ceramics are widely used in modern industry and life. Here we briefly introduce its main application areas.
1. 3C electronics such as mobile phones
Zirconia ceramics have no signal shielding, drop resistance, wear resistance and fold resistance. At the same time, they have a warm appearance like jade and a good feel. They are widely used in mobile phones and other 3C electronic fields. Mainly used as mobile phone backplane and other mobile phone structural parts.
2. The field of smart wear
Compared with metal, zirconia ceramics have better wear resistance, and the surface is smooth, the texture is good, and it is not oxidized. Famous Swiss brands such as "Radar", Apple, Chanel and others have launched high-end ceramic watches.
3. Optical communication field
At present, ceramic ferrules and sleeves are widely used in optical fiber connectors. The ceramic ferrules made of high-strength and high-toughness ceramic not only meet the requirements of high precision, but also have a long service life and very low insertion loss and return loss.
4. Biomedical field
Zirconia ceramic materials are the most common applications in the field of biomedicine as dental restoration materials and surgical knives due to their high strength, high toughness, corrosion resistance, wear resistance, and good biocompatibility.
5. Automotive
The thermal conductivity coefficient of zirconia ceramics is small, and the thermal expansion coefficient is relatively large, so the components used to make the engine combustion chamber have good thermal insulation, and at the same time, they are closer to metal materials in thermal expansion. It can be used as cylinder head bottom plate, cylinder liner, 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 some distance from commercial applications.
6. Jewelry field
High-precision ceramics and precious metal alloy powder are mixed and fired, and after several precise and strict procedures and multiple machine grinding and polishing, they are finally integrated into jewelry design. This ceramic is not only light and wear-resistant, but also has anti-sensitivity characteristics and is comfortable to wear. It is one of the most fashionable jewelry materials nowadays, and it is favored by major jewelry brands.
7. Fields of daily life
Ceramics are the inheritance of Chinese culture for thousands of years. In addition to the above applications, ceramics are everywhere in our daily lives. Ceramics have the characteristics of high temperature resistance, corrosion resistance, oxidation resistance, high strength, wear resistance, and natural antibacterial properties. They can be used as porcelain bowl spoons, vases, ceramic knives, etc.
8. Other fields
Zirconia ceramics have good mechanical properties, wear resistance and corrosion resistance, and can be used as ceramic bearings or ceramic tools. At the same time, zirconia ceramics are weakly acidic oxides, which can resist the erosion of the calculated or neutral slag (but will be eroded 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 petroleum, chemical, machinery, aviation and other fields.
