Speaking of new materials, zirconia ceramics have to be said, because zirconia ceramics have high toughness, high bending strength, high wear resistance, corrosion resistance, excellent thermal insulation properties, thermal expansion coefficient close to steel and environmental protection. The main product categories are: mechanical structural parts, Y-TZP grinding balls, dispersion and grinding media, nozzles, ball valve ball seats, zirconia molds, miniature fan shafts, optical fiber pins, optical fiber sleeves, drawing dies and cutting tools, wear-resistant Knives, clothing buttons, watch cases and straps, bracelets and pendants, ball bearings, light golf bats and other wear-resistant components. In functional ceramics, its excellent high temperature resistance is used as induction heating tubes, refractory materials, and heating elements. Zirconia ceramics have sensitive electrical performance parameters and are mainly used in fields such as oxygen sensors, solid oxide fuel cells (SOFC), and high-temperature heating elements. ZrO2 has a high refractive index (N-21 ^ 22), adding certain coloring elements (V2O5, MoO3, Fe2O3, etc.) to the ultra-fine zirconia powder, which can be made into colorful translucent polycrystalline ZrO2 Like a natural gemstone, it flashes a colorful light and can be made into various decorations. In addition, zirconia is widely used in the fields of thermal barrier coatings, catalyst carriers, medical treatment, health care, refractory materials, aerospace, petrochemicals, new energy, robotics, electrical appliances, and textiles.
