With the continuous development of technology and mankind, people's pursuit and improvement of life, and industry's continuous demand for product quality, zirconia ceramics are more widely used in modern industry and life. Now, let us briefly introduce its main application areas.
1. 3C electronic fields such as mobile phones
Zirconia ceramics are widely used in 3C electronic fields such as mobile phones because of their advantages such as no signal shielding, drop resistance, wear resistance, folding resistance, warm and smooth appearance, and good hand feeling. Mainly used as mobile phone backplane and other mobile phone structural parts.
Compared with metals, zirconia ceramics have better wear resistance, smooth surface, good texture, and no oxidation. Famous Swiss brands such as Radar, Apple and Chanel have all launched high-end ceramic watches.
3. Optical communication field
At present, ceramic ferrules and sleeves are widely used in optical fiber connectors. The ceramic ferrule made of high-strength, high-toughness ceramics not only meets the requirements of high precision, but also has a long service life and extremely low insertion loss and return loss.
4. the biomedical field
Zirconia ceramic materials are widely used in the biomedical field as dental restoration materials and surgical tools due to their high strength, high toughness, corrosion resistance, wear resistance and good biocompatibility.
5. the automotive field
Zirconia ceramics have a small thermal conductivity and a relatively large thermal expansion coefficient, so the parts used to manufacture the engine combustion chamber have good thermal insulation properties and are close to metal materials in terms of 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 a long way to go before commercial applications.
6. Jewelry field
High-precision ceramics and precious metal alloy powders are mixed and fired, after several precise and strict processes and multiple machines are polished, and finally integrated into the jewelry design. This kind of ceramic is not only light weight, wear-resistant, but also has the characteristics of anti-sensitivity and is 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 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 cultural heritage of China for thousands of years. In addition to the above applications, ceramics are also ubiquitous in our daily lives. Ceramic has the characteristics of high temperature resistance, corrosion resistance, oxidation resistance, high strength, wear resistance and natural antibacterial. It can be used as bowls, spoons, vases, ceramic knives, etc.
