Eight major application areas of zirconia ceramics in daily life
Zirconia ceramics are widely used in modern industry and daily life. Here is a brief introduction to its main application fields.
1. 3C mobile phones and other electronic fields
Zirconia ceramics are widely used in 3C electronic fields such as mobile phones due to their advantages of no signal shielding, anti-fall, wear resistance, folding resistance, warm and smooth appearance, and good feel. Mainly used as mobile phone backplanes and other mobile phones Structure.
2. Smart wearable field
Compared with metal, zirconia ceramic has better wear resistance, smooth surface, good texture, and no oxidation. Well-known Swiss brands such as Radar, Apple, and Chanel have launched high-end ceramic watches.
3. Optical communication field
Nowadays, ceramic inserts and ferrules are widely used in fiber optic connectors. Ceramic ferrules made of high-strength, high-toughness ceramics not only meet high-precision requirements, but also have long service life and extremely low insertion and return losses.
4. Biomedical field
Zirconia ceramic materials are widely used in the biomedical field as dental restorative materials and surgical tools due to their high strength, high toughness, corrosion resistance, wear resistance, and good biocompatibility.
5. Automobile industry
Zirconia ceramic has a small thermal conductivity and a relatively large thermal expansion coefficient, so the components used to manufacture engine combustion chambers have good thermal insulation properties and are close to metal materials in terms of thermal expansion. They can be used as cylinder head bottom plates, cylinder liners, piston crowns, valves Seat rings, etc. However, due to the harsh operating conditions of the engine, the strength of ceramic components changes greatly at high temperatures, so it is still some way away from commercial application.
6. Jewelry field
High-precision ceramics and precious metal alloy powders are mixed and fired, undergo several precise and rigorous processes, and are polished by multiple machines, and are finally integrated into jewelry designs. This ceramic is not only lightweight and wear-resistant, but also has anti-sensitivity characteristics. Comfortable to wear. It is currently one of the most fashionable jewelry materials and is favored by major jewelry brands. Many luxury brands such as Bulgari Classic B.Zero1 and Save the Children series, Chanel Ultra series, Cartier, etc. In their Ceramic materials have been used in jewelry.
7. Daily life areas
Ceramics are the inheritance of Chinese culture for thousands of years. In addition to the above-mentioned applications, ceramics are also ubiquitous in our daily lives. Ceramics have the characteristics of high temperature resistance, corrosion resistance, oxidation resistance, high strength, wear resistance and natural Antibacterial, and can be used as bowls, 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 that can resist the erosion of acidic or neutral slag (but can corroded by alkaline slag), and can be made into refractory crucibles for metallurgy. The high strength, high toughness, and corrosion resistance of zirconia ceramics also make it have certain applications in fields such as petroleum, chemical engineering, machinery, aviation, etc.
