About 60 years ago,Zirconium oxide ceramicIndustrial applications are far from being developed. After about the 1970s, large-scale research on the application of zirconia ceramics began all over the world because it shows excellent performance in engineering applications.
Ceramic rod zirconia ceramic is a new type of ceramic with very excellent physical and chemical properties. It has not only become a research hotspot in the field of scientific research, but also has been widely used in industrial production. It is a refractory Materials, high-temperature structural materials and important raw materials for electronic materials. Among various metal oxide ceramic materials, zirconia has the best high-temperature thermal stability and thermal insulation properties, and is most suitable for ceramic coatings and high-temperature refractory products.
Zircon-based ceramic pigments with zirconia ceramics as the main raw material are important components of high-grade glazes; the thermal conductivity of zirconia is the lowest among common ceramic materials, and The thermal expansion coefficient is close to that of metal materials, making it an important structural ceramic material; its special crystal structure makes it an important electronic material;
Zirconium oxide ceramic's phase change toughening and other characteristics have made it the favorite of plastic ceramic materials; its good mechanical properties and thermophysical properties make it an excellent metal matrix composite material the enhancement phase.
Since Gupta first reported the tetragonal zirconia ceramic TZP, research on TZP materials has been in the ascendant. TZP ceramic is a material with the highest room temperature mechanical properties among zirconia toughened ceramics.
Its strength and fracture toughness can be as high as 1. 5GPa and 1 5MPa/m2. Its hardness, wear resistance and chemical corrosion resistance are also good. It is often used in harsh environments and Severe load conditions, such as wire drawing dies, bearings, seals and replacement human bones, as well as engine piston crowns, cams in valve trains, fiberglass and tape cutters, etc.
