Zirconia ceramics are widely used in modern industry and life.
3C Electronic Field such as Mobile Phone
Zirconia ceramics are widely used in the 3C electronic field, such as mobile phones, because of their non-signal shielding, anti-wear, anti-breaking, moist appearance, and a good handle. It is mainly used for mobile phone backplane and other mobile phone structural parts.
Intelligent Wearing Field
Compared with metals, zirconium crystals have better wear resistance, smooth surface, good texture, and no oxidation. Switzerland's famous "radar" brand, Apple, Chanel, and other well-known brands have launched high-end ceramic watches.
Optical communication field
At present, ceramic sockets and sleeves are widely used in connectors of optical fiber connectors. Ceramic cores with high strength and toughness can not only meet the requirements of high precision but also have a long service life and very low insertion loss and echo loss.
Biomedical field
Because of its high strength, high toughness, corrosion resistance, wear resistance and good biocompatibility, zirconia ceramics are widely used as dental restorative materials and surgical tools in the field of biomedicine.
Automotive field
The thermal conductivity of zirconia ceramics is small, but the thermal expansion coefficient is relatively large, so it has good thermal insulation for engine combustion chamber parts, and at the same time, the thermal expansion of zirconia ceramics is close to that of metal materials. It can be used as the bottom plate of the cylinder head, cylinder liner, piston top, valve seat ring, etc. However, due to the rigorous working conditions of the engine, the strength of ceramic components varies greatly at high temperatures, so there is still a long way to go from commercial applications.
Jewelry field
High precision ceramics and precious metal alloy powders are mixed firing, and after several precise and strict procedures and multiple machine polishing and polishing, they are finally integrated into jewelry design. This kind of ceramics is not only lightweight and wearable but also sensitive and comfortable to wear. It is one of the most fashionable jewelry materials and is favored by major jewelry brands.
Ceramic materials are used in many luxury brands such as Chanel Ultra and Cartier.
The Field of Daily Life
In addition to the above applications, ceramics are also ubiquitous in our daily life. Ceramics have the characteristics of high-temperature resistance, corrosion resistance, oxidation resistance, high strength, wear resistance, and natural anti-bacterial. They can be used as ceramic spoons, vases, ceramic knives, etc.
Other fields
Zirconia 702 has good mechanical properties, wear resistance and corrosion resistance. They can be used as ceramic bearings and ceramic cutting tools. At the same time, zirconia ceramics are weak acidic oxides, which can resist calculating or neutral slag erosion (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 make yttria stabilized zirconia have certain applications in petroleum, chemical industry, machinery, aviation, and other fields.
