Performance and Cost Advantages of Zirconia Ceramics

Zirconia ceramic is a new type of high-tech ceramics, which not only has the conditions of high strength, hardness, high-temperature resistance, acid, and alkali corrosion resistance, and high chemical stability, but also has higher toughness than ordinary ceramics.

Zirconia ceramic is a new type of high-tech ceramics, which not only has the conditions of high strength, hardness, high-temperature resistance, acid, and alkali corrosion resistance, and high chemical stability, but also has higher toughness than ordinary ceramics.

zirconia ceramics are also used in various industries, such as shaft seal bearings, cutting components, molds, auto parts, etc., and even can be used in the human body, such as artificial joints.

In the field of consumer electronics, zirconia ceramics are favored by fingerprint identification module patches and mobile phone backboards because their hardness is close to that of sapphires, but the total cost is just a quarter of sapphires, its folding resistance is higher than that of glass and sapphires, and its dielectric constant is between 30 and 46, which is non-conductive and does not shield signals.

First, from the perspective of chemical properties: zirconia ceramics show absolute inertia, acid and alkali resistance, non-aging, far more than plastics and metals.

Second, from the perspective of communication performance, the dielectric constant of zirconia is 3 times that of sapphire, and the signal is more sensitive, which is more suitable for fingerprint identification patches.

From the perspective of shielding effectiveness, zirconia ceramic as a non-metallic material has no shielding effect on electromagnetic signals, will not affect the internal antenna layout, and can be easily integral molded.

Third, from the point of view of physical properties: ceramics have strong vitality as the structural parts of consumer electronics. Especially for zirconia ceramics, it has been proved to be an excellent structural material in many fields, such as optical communication, industry, medical treatment, and so on. It has entered the field of consumer electronics, but it is the natural result of the reduction of cost and the improvement of brittleness.

In terms of hardness, the Morse hardness of zirconia ceramics is about 8.5, which is very close to that of sapphire 9, while that of polycarbonate is only 3.0, that of toughened glass is 5.5, that of aluminum-magnesium alloy is 6.0, and that of Corning glass is 7.0.
