Precision Ceramics: Invisible Guardians in Modern Life

In today's rapidly advancing technology, a seemingly unfamiliar yet ubiquitous material - Advanced Ceramics - is quietly changing our daily lives. From smartphones to medical devices, from kitchen utensils to transportation vehicles, this high-performance material that combines traditional ceramic aesthetics with modern technological characteristics is playing an irreplaceable role in various fields.

• What is precision ceramic?

Precision ceramics, also known as high-performance ceramics or engineering ceramics, are a new type of inorganic non-metallic material made by strictly controlling the composition and microstructure. Unlike traditional ceramics, precision ceramics use high-purity raw materials such as alumina, zirconia, silicon nitride, etc., and are made through advanced molding and sintering processes, possessing excellent mechanical, thermal, electrical, and biological properties.

• Application of Precision Ceramics in Daily Life

1. In the field of electronic communication

In the smartphones that modern people cannot do without, precision ceramics play multiple roles. Zirconia ceramics are widely used in mobile phone backplates and fingerprint recognition modules due to their excellent dielectric properties and wear resistance. The piezoelectric ceramics in mobile phones are responsible for achieving vibration feedback and sound conduction. The filters in 5G communication base stations also extensively use precision ceramic materials with low dielectric loss.

2. Medical and health field

In the medical field, precision ceramics shine brightly due to their excellent biocompatibility. Zirconia ceramics are used to make dental crowns and bridges, which are not only aesthetically pleasing and durable, but also do not cause allergic reactions. Artificial joints and bone repair materials often use specially treated ceramic materials. Even more astonishing is that some miniature ceramic sensors have been implanted into the body to monitor patients' physiological indicators in real-time.

3. In the field of home life

Entering a modern kitchen, the figure of precision ceramics can be seen everywhere. Ceramic cutting tools are favored for their superior hardness and antibacterial properties, and do not produce odors or rust like metal cutting tools. The microcrystalline ceramic panel in the induction cooker can withstand rapid temperature changes. Even the nano ceramic glaze on the surface of our daily toilets can effectively inhibit bacterial growth.

4. Personal care field

Beauty enthusiasts may not know that many of the beauty devices they use every day use precision ceramic components. Far infrared ceramics can uniformly generate heat and are used in facial care instruments; Micro porous ceramics are used in the sustained-release systems of some high-end skincare products. Even the brush heads of electric toothbrushes are made of antibacterial ceramic materials.

5. Transportation and travel field

The rapid development of new energy vehicles cannot be separated from the contribution of precision ceramics. The ceramic separator in lithium-ion batteries improves the safety of the battery; Zirconia ceramic components in oxygen sensors help optimize engine combustion efficiency. Even the braking system of high-speed trains uses special ceramic composite materials.

• The unique advantages of precision ceramics

The reason why precision ceramics can replace traditional materials in many fields is mainly due to their unique combination of properties:

✳Extremely high hardness and wear resistance

✳Excellent high temperature resistance and corrosion resistance

✳Good insulation or conductivity properties (can be designed according to requirements)

✳Excellent biocompatibility

✳Environmentally friendly and recyclable

• Future prospects

With the advancement of materials science, the application fields of precision ceramics are constantly expanding. Scientists are developing smart ceramics with self-healing capabilities, biodegradable bioceramics, and new ceramic materials with superconducting properties. These innovations will further enhance our quality of life.
