Zirconia Ceramic Products
Description
Zirconia ceramics, ZrO2 ceramics, Zirconia Ceramic have excellent properties such as high melting point and boiling point, high hardness, insulator at room temperature, and electrical conductivity at high temperature.
Applications of Zirconia Ceramics
Zirconia ceramics are widely used in the field of structural ceramics because of their high toughness, high flexural strength and high wear resistance, excellent thermal insulation properties, and thermal expansion coefficient close to steel. Mainly include: Y-TZP grinding balls, dispersing and grinding media, nozzles, ball valve seats, zirconia molds, miniature fan shafts, fiber optic pins, fiber optic sleeves, drawing dies and cutting tools, wear-resistant knives, clothing buttons, Cases and straps, bracelets and pendants, ball bearings, light bats for golf balls, 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 ultra-fine zirconia powder, it can be made into colorful translucent polycrystalline ZrO2 materials , shining like a natural gemstone with brilliant and colorful light, it can be made into a variety of decorations. In addition, zirconia is being widely used in thermal barrier coatings, catalyst carriers, medical care, health care, refractories, textiles and other fields.
