Zirconia Ceramics
Industrial manufacturing: It can be used as a coating material for engine parts. Due to its high temperature resistance and good heat insulation performance, it can effectively protect the internal parts of the engine, improve the thermal efficiency and reliability of the engine, and reduce energy consumption. It has important applications in the fields of automobiles and aircraft engines, and has promoted the development of engine technology and performance improvement.
Medical equipment: The compatibility of ceramics with the human body makes it indispensable in the replacement of human teeth, bones, and joints. At the same time, because of the self-lubricating characteristics of the material, the good surface density, easy polishing, and the presence of pure white color, it is also widely used in fine grinding medical parts such as plungers and seals.
Jewelry field: Zirconia ceramics have high hardness, high refractive index and good glossiness. They are often used to make imitation diamond jewelry. Its appearance is very similar to diamonds, but the cost is relatively low. It is deeply loved by consumers and meets the public's demand for beautiful and durable jewelry. It occupies a certain share in the fashion jewelry market.
