Application of zirconia ceramics

In terms of structural ceramics, zirconia ceramics are widely used in the field of structural ceramics because of their high toughness, high bending strength, high wear resistance, excellent thermal insulation performance, and thermal expansion coefficient close to steel. Mainly include: Y-TZP grinding balls, dispersion and grinding media, nozzles, ball valve seats, zirconia molds, micro 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 batting sticks, and other room temperature wear-resistant parts.

In terms of 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 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 ultrafine zirconia powder can be made into a colorful translucent polycrystalline ZrO2 material , Shining brilliantly and colorfully like natural gemstones, and can be made into various decorations. In addition, zirconia is widely used in thermal barrier coatings, catalyst carriers, medical treatment, health care, refractory materials, textiles and other fields.
