Zirconia ceramics are widely used in modern industry and life. Let us briefly introduce its main application areas.
1. Mobile Phones And Other 3C Electronic Fields
Zirconia ceramics have no signal shielding, drop resistance, wear resistance and folding resistance. At the same time, the appearance is warm and moist like jade, and the hand feel is good. It is widely used in the field of 3C electronics such as mobile phones. Mainly used for mobile phone backplane and other mobile phone structural parts.
2. The Field Of Smart Wear
Compared with metal, zirconia ceramics have better wear resistance, smooth surface, good texture and no oxidation. The famous Swiss “Radar” brand, Apple, Chanel and other well-known brands have launched high-end ceramic watches.
3. The Field Of Optical Communication
At present, ceramic ferrules and sleeves are widely used in optical fiber connectors. Ceramic ferrules made of high-strength and high-toughness ceramics can 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
Due to its high strength, high toughness, corrosion resistance, wear resistance and good biocompatibility, zirconia ceramic materials are most commonly used in the biomedical field as dental restoration materials and surgical tools.
5. Automotive Field
The thermal conductivity of zirconia ceramics is small, and the thermal expansion coefficient is relatively large, so the parts used to make the engine combustion chamber have good heat insulation, and at the same time, the thermal expansion is closer to that of metal materials. 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 parts changes greatly at high temperatures, so there is still a distance from commercial application.
6. Jewelry
High-precision ceramics are mixed with precious metal alloy powder and fired, and are finally integrated into jewelry design after several precise and strict procedures and repeated machine grinding and polishing. This ceramic is not only lightweight and wear-resistant, but also has anti-allergic 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.
Many luxury brands such as Bulgari classic series B.Zero1 and Save The Children series, Chanel Ultra series, Cartier and other jewelry have applied ceramic materials.
7. Areas Of Daily Life
Ceramics are the inheritance of thousands of years of Chinese culture. In addition to the above applications, ceramics are ubiquitous in our daily life. Ceramic has the characteristics of high temperature resistance, corrosion resistance, oxidation resistance, high strength, wear resistance, and natural antibacterial properties, which can be used as porcelain bowls, vases, ceramic knives, etc.
8. Other Fields
Zirconia ceramics have good mechanical properties, wear resistance and corrosion resistance. They can be used as ceramic bearings and can also be made into ceramic tools. At the same time, zirconia ceramics are weakly acidic oxides, which can resist the erosion of low 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, mechanical, aviation and other fields.
