What is Zirconia Ceramics? What are the advantages?

What is Zirconia Ceramics? What are the advantages? Do you know the answers to these two questions? Next, Pintejin Ceramics, a manufacturer specializing in the production of zirconia ceramics, will focus on introducing zirconia ceramics.

Zirconia ceramic tube What is zirconia ceramic: Zirconia ceramic is white, yellow or gray when it contains impurities, generally contains HfO2, and is not easy to separate. There are three crystalline states of pure ZrO2 under normal pressure. The production of zirconia ceramics requires the preparation of powders with high purity, good dispersion properties, ultra-fine particles and narrow particle size distribution. There are many preparation methods for zirconia ultra-fine powder. The purification of zirconia mainly includes chlorination and thermal decomposition, alkali metal Oxidative decomposition method, lime melting method, plasma arc method, precipitation method, colloid method, hydrolysis method, spray pyrolysis method, etc.

It is understood that zirconia ceramics is a new type of high-tech ceramics. In addition to the high strength, hardness, high temperature resistance, acid and alkali corrosion resistance and high chemical stability that precision ceramics should have, it also has higher toughness than ordinary ceramics. , so that zirconia ceramics are also used in various industries, such as shaft seal bearings, cutting components, molds, auto parts, etc., and can even be used in the human body, such as artificial joints. In the field of consumer electronics, zirconia ceramics have a hardness close to that of sapphire, but the total cost is less than 1/4 of that of sapphire. Its refractive index is higher than that of glass and sapphire. Its dielectric constant is between 30-46. Therefore, it is favored by fingerprint identification module patches and mobile phone backplanes.

Zirconia ceramic rods The advantages of zirconia ceramics are: 1. From the perspective of chemical properties: zirconia ceramics are absolutely inert, resistant to acid and alkali, and do not age, far exceeding plastics and metals. 2. From the perspective of communication performance: the dielectric constant of zirconia is 3 times that of sapphire, the signal is more sensitive, and it is more suitable for fingerprint identification patches. From the perspective of shielding effectiveness, zirconia ceramics as a non-metallic material have no shielding effect on electromagnetic signals, and will not affect the internal antenna layout at all, and can be easily integrated into one. 3. From the perspective of physical properties: ceramics have strong vitality as a structural component 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, and medical treatment.

It has entered the field of consumer electronics, but it is the result of its cost reduction and brittleness improvement. In terms of hardness, the Mohs hardness of zirconia ceramics is about 8.5, which is very close to the Mohs hardness of sapphire 9, while the Mohs hardness of polycarbonate is only 3.0, the Mohs hardness of tempered glass is 5.5, and the Mohs hardness of aluminum-magnesium alloys is 5.5. 6.0, and Corning Glass has a Mohs hardness of 7. Pintejin Ceramics is a professional manufacturer of industrial ceramics, mainly engaged in the research and development and production of zirconia ceramics and alumina ceramics. We can process ceramic products according to your drawings, specializing in the production of high-precision ceramic rods, ceramic tubes, ceramic rings, ceramic plates, ceramic flanges, ceramic nozzles, and customized precision ceramic parts, etc.
