Ceramic material comparison
The mobile phone shell uses chemical zirconia ceramics. At present, the biggest question about its application on mobile phones is its high cost. But as the saying goes, you get what you pay for. If you compare it with the relatively low-priced alumina ceramics, you can find many of its advantages:
Ceramic toughness comparison
The toughness of chemical zirconia ceramics is 4 times that of alumina ceramics. At the same time, the chemical zirconia will only be chipped while falling freely from a height of one meter and chemical alumina will be broken.
Density comparison
The density of chemical zirconia ceramics is twice that of alumina ceramics. In contrast, chemical zirconia has better compressive performance.
Friction coefficient comparison
The friction coefficient of chemical zirconia ceramics is only 1/2 of that of alumina ceramics, but in the actual use process, more considerations are given to the amount of elastic wear and hard wear. Which material is more wear-resistant depends on the actual usage.
Density contrast
The density of the chemical zirconia ceramic structure is higher than that of the alumina ceramic, the density of the alumina ceramic is 3.5, the density of the zirconia ceramic structure is 6, and the texture is more delicate.
Surface finish comparison
After grinding, the chemical zirconia ceramic structure has a higher surface finish, which can reach ▽9 or more. It is mirror-like, extremely smooth, and has less friction with the net, which can further increase the service life of the net and greatly reduce the net. Consumption, reduce the current of the paper network, reduce power consumption.
In addition, the toughness of chemical zirconia ceramic structural parts is excellent, which overcomes the inherent brittleness of the ceramic itself, has higher wear resistance, greatly prolongs the service life of the product, and significantly improves the quality of the paper. At the same time, it is also suitable for fingerprint identification (just needed) .
During production, zirconia ceramics can be directly prepared by casting and other processes, which is not only simple, but also work efficiency and productivity can be greatly improved. It can also have the color and texture of jade through toning, and the color can be changed. In addition to the back panel of mobile phones, it can also be used in high-end consumer electronics products to improve the grade.
