Zirconia ceramics are known as “ceramic steel” because of their high hardness, wear resistance and high fracture toughness. After the product is polished, the texture is like jade, especially after Apple introduced Apple Watch, it is bound to detonate the application of 3C market.

Characteristics of zirconia nano ceramics

Good mechanical properties:
High hardness, close to sapphire, abrasion resistant, scratch resistant
High flexural strength and good toughness, twice the sapphire
Elements, safe, and widely available:
Has been applied in batches in machinery, communication, modification, chemical, medical, new energy, aviation and other fields
High processability:
Dimensional accuracy up to +/-0.002%, low processing cost
Good electrical performance:
The dielectric constant is three times that of sapphire, and the signal is more sensitive.
Suitable for mass production:
The key technology of localization of nano-powder has been broken, meeting the mass production of ceramics
Skin-friendly, good appearance:
Low thermal conductivity, environmental protection, strong jade texture, can also be manually colored by adding rare earth elements; good compactness and good surface finish

Reasons for choosing zirconia nano ceramics for smart wear and mobile appearance parts

1. Nano zirconium dioxide ceramics have a high dielectric constant at room temperature, have little effect on microwave signals and micro-sensing signals, and have functional advantages.

2. The nano-zirconia has a jade-like texture after polishing. It is a high-end decorative material that is second only to gemstones in appearance decoration materials, and has a visual aesthetic.

3. High hardness, not easy to wear, compared with spray, anode, PVD to overcome the uncomfortable problems of discoating, fading, wear, etc., have a comparative advantage.

4. Nano-ceramics have good compatibility with human body, are not easy to produce bacteria, are not allergic to skin, and have environmental health care functions.

5. Zirconium dioxide is the most excellent comprehensive mechanical property in ceramic materials. It fully meets the requirements of civilian use. At present, there is no alternative material, and it has the advantage of long market life cycle.

6. The development of near-forming technology of powder materials such as zirconia CIM and the improvement of ceramic CNC processing technology have solved the problem of difficult processing and mass production of hard materials. As the industry expands, automated processing and polishing equipment will follow. There is no concern about product accuracy and mass production.

7. How to polish China’s (continental) hard materials, the technology is world-class, the ability to reduce costs is also first-class, the space for cost reduction is still very large, the increase in the number of market use and the reduction of cost will be benign interaction, the price is not a problem .
