Due to its high hardness (around HV1400), zirconia ceramic materials have certain requirements for the processing and polishing of raw materials. Our company adheres to the excellent technology of processing sapphires with higher hardness and has formed a quality system specifically for processing and polishing zirconia, which has the characteristics of high yield, good accuracy, and high degree of automation.

In addition, due to the company's existing sapphire quality system, we have strict requirements for the appearance quality of zirconia, and our current comprehensive evaluation has considerable advantages.

Zirconia ceramics:

Compared with metals and plastics, zirconia ceramic materials have the advantages of wear resistance, skin affinity, good air tightness, low electromagnetic shielding, high hardness, high dielectric constant, and low cost, making them more suitable for use in wearable devices.

The main characteristics and applications of sapphire lenses are as follows:

Generally, wearable devices require good airtightness and waterproofing, and wireless charging is necessary. Based on the above advantages, using ceramic materials for the back cover is obviously superior to metal materials. Zirconia ceramics can have the color and texture of jade through color matching, with a variety of colors, and can be applied in high-end consumer electronics products such as ceramic smart rings.

Basic characteristics of zirconia ceramics:

① High hardness, Vickers hardness of 1300-1400, wear-resistant, scratch resistant;

② Dielectric constant of 26-35, more sensitive to signals and data;

③ There are various molding methods, and the production capacity can be rapidly expanded;

④ Low human rejection, good skin affinity, can be worn or implanted close to the body;

⑤ Among materials of the same hardness, the fracture toughness is the highest and the bending strength is the highest;

⑥ The available colors are quite diverse;

⑦ Good insulation and electrical isolation, capable of wireless charging;
