According to the latest data from IDC, although suppliers have reduced production scale due to the impact of the epidemic, demand for wearable devices remains stable. As zirconia ceramic structural parts that are widely used in wearable devices, they have high temperature resistance, high strength, super hardness, wear resistance, and It corrodes, can be polished, looks beautiful and is low cost, which is favored by suppliers.
As a smart material, the advantages of zirconia ceramics are:
1. High hardness and wear resistance
From the perspective of the hardness of zirconia ceramics, the Mohs hardness of zirconia ceramics is about 8.5, which is very close to the Mohs hardness of sapphire 9. It is harder than metal. And glass used in daily life is not prone to scratches or scratches. Compared with anodes, PVD overcomes the inconvenient problems of pickling, fading and wear and has comparative advantages.
2. Skin-friendly, non-allergenic
Steel watches contain nickel and other substances. The chemical components (salt ions) in sweat cause these metals in the watch case toMetallic elements are more active (ionized) and cause skin abnormalities. Ceramic materials have no precipitated metal ions, and because of their low thermal conductivity, they are less likely to cause allergies when used. They are more skin-friendly than metals and plastics, have good compatibility with the human body, and are not prone to bacteria.
3. Good heat dissipation and heat dissipation
It has good heat dissipation and uniformity, effectively solves the heat conduction problem of the equipment, and is the best solution for heat dissipation.
4. Jade texture, warm color
Zirconia ceramics have the color and texture of jade, which can be artificially adjusted by adding rare earth elements to make the color changeable and beautiful, which can improve product quality and consumer appeal. Zirconia ceramic has a jade-like texture after polishing. This is a high-end decorative material that surpasses only gemstones and has visual beauty.
5. Do not block signals
The dielectric constant of zirconia ceramic is 3 times that of sapphire, the signal is more sensitive, electrically isolated, can be charged wirelessly without signal protection, and supports positioning of smart devices, phone calls, payment and signal functions.
6. Suitable for mass production and low cost
The key nanopowder positioning technology that meets the mass production of nanoceramics has achieved a breakthrough. Molding methods for mass production include dry pressing, injection, tape casting and gel injection molding, and production costs Low.
