日常生活におけるジルコニアセラミックスの8つの主要な応用分野

日常生活におけるジルコニアセラミックスの8つの主要な応用分野

Zirconia ceramics are widely used in modern industry and daily life. Let’s 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 due to their advantages of no signal shielding, アンチドロップ, 耐摩耗性, 耐折性, 暖かく滑らかな外観, そして良い手触り. Mainly used as a mobile phone backplane and other mobile phone structural components.

2、 Intelligent wearable field

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

目下, ceramic inserts and sleeves are widely used in fiber optic connectors. Ceramic ferrules made of high-strength and high toughness ceramics not only meet high-precision requirements, but also have a 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, 高い靭性, 耐食性, 耐摩耗性, and good biocompatibility.

5、 Automotive sector

Zirconia ceramics have small thermal conductivity and relatively large coefficient of thermal expansion, so the components used to manufacture engine combustion chambers have good thermal insulation performance, and are close to metal materials in terms of thermal expansion. Can be used as cylinder head base plate, cylinder liner, piston crown, valve seat ring, 等. しかし, due to the harsh working conditions of the engine, the strength of ceramic components varies greatly at high temperatures, so there is still some distance from commercial application.

6、 Jewelry field

High precision ceramics and precious metal alloy powders are mixed and fired, undergo several precise and strict processes, and are polished by multiple machines, ultimately integrated into jewelry design. This type of ceramic is not only lightweight and wear-resistant, but also has the characteristics of resistance to sensitivity, making it 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 the Bulgari Classic B.Zero1 and Save The Children series, Chanel Ultra series, Cartier, 等. have used ceramic materials in their jewelry.

7、 Field of daily life

Ceramics are the heritage of thousands of years of Chinese culture. In addition to the above applications, ceramics are also ubiquitous in our daily lives. Ceramics have the characteristics of high temperature resistance, 耐食性, 耐酸化性, 高強度, abrasion resistance and natural antibacterial, and can be used as bowls, spoons, vases, ceramic knives, 等.

8、 Other fields

Zirconia ceramics have good mechanical properties, wear resistance and corrosion resistance, and can be used as ceramic bearings or ceramic tools. Meanwhile, zirconia ceramics are weakly acidic oxides that can resist the erosion of acidic or neutral slag (but can be eroded by alkaline slag), and can be made into refractory crucibles for metallurgy. The high strength, 高い靭性, and corrosion resistance of zirconia ceramics also make them have certain applications in fields such as petroleum, 化学工学, machinery, aviation, 等.
