What Are the Applications of Nano-composite Zirconia?

Nano-composite Zirconia is a ceramic material doped with metal oxides with acid, alkali, oxidation and reducing properties. The doped stable zirconia has good properties in mechanics, heat, electromagnetics, and optics, and has important applications in catalysis.

Denture material

Nano-composite zirconia can improve the strength of ceramics at room temperature and the stress intensity factor obviously so that the toughness of ceramics can be improved multiple times. The composite bioceramics prepared by nano zirconia have good mechanical properties, chemical stability and biocompatibility, which is a promising composite bioceramics material, especially in dental materials and artificial joints. As a kind of fine bioinert ceramic, it has excellent chemical stability both as oral prosthesis and implant, and it completely meets the standard of the oral prosthesis.

Nano-composite Zirconia

Oxygen sensor

The sensor made of zirconium oxide has good electrical conductivity and plays an important role in controlling automobile exhaust and burning of power plant boilers. The zirconium oxide oxygen sensor is one of the most mature and productive oxygen sensors, which is one of the key components in the automobile emission control system, and the signal output characteristics of which can affect the fuel economy and emission control of the engine directly.

Automobile exhaust purification catalyst

Automobile exhaust purification catalysts are generally composed of the carrier, auxiliary catalyst, among which zirconium-cerium solid solution composite oxide materials are very important coating materials as catalysts. Besides that, zirconium-cerium solid solution is widely used in sensor materials, polishing materials, fuel cells, structural materials and high strength ceramics.

Mobile terminal products

With the approach of 5G, wireless charging and other new transmission modes, wireless frequency band become more and more complex, and metal casing shielding will become a major bottleneck. The strict 5G antenna layout requires changing the existing metal shell material, so ceramics and glass will be optional. Moreover, metal materials are also very unfriendly to wireless charging technology. At present, most wireless charging technologies use electromagnetic materials, and metal will cause interference to electromagnetic waves, which greatly reduces the charging efficiency. Plastic is prone to scratches and glass is fragile, and ceramic materials are gradually penetrating into the appearance of smartphones due to their excellent physical properties.
