Zirconia ceramic is a white ceramic material that appears yellow or gray when it contains impurities, typically including HfO2, which is difficult to separate. Zirconia ceramic is an extremely durable ceramic material that possesses excellent hardness, fracture toughness, and corrosion resistance. It has high strength, toughness, wear resistance, and corrosion resistance, making it suitable for use in operating environments where plastics, metals, and other ceramic materials cannot withstand.

What’s the application？
Zirconia ceramics have unique chemical bonds and crystal structures, making them useful in high-temperature, electrical, mechanical, and optical fields. They can be broadly divided into two application fields: structural ceramics and functional ceramics. In structural ceramics, zirconia ceramics are widely used due to their high toughness, high bending strength, high wear resistance, excellent insulation performance, and thermal expansion coefficient close to that of steel. Examples of applications include Y-TZP grinding balls, dispersants 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 tools, clothing buttons, watch cases and straps, bracelets and pendants, ball bearings, lightweight golf club heads, and other room temperature wear-resistant components. In functional ceramics, zirconia ceramics are used for their excellent high-temperature resistance as induction heating tubes, refractory materials, heating elements, etc. Zirconia ceramics also have sensitive electrical properties and are mainly used in fields such as oxygen sensors, solid oxide fuel cells (SOFCs), and high-temperature heating elements. ZrO2 has a high refractive index (N-21^22), and by adding certain coloring elements (V2O5, MoO3, Fe2O3, etc.) to ultrafine zirconia powder, it can be made into colorful translucent polycrystalline ZrO2 materials that sparkle with brilliant colors like natural gemstones, and can be made into various decorations. In addition, zirconia is widely used in fields such as thermal barrier coatings, catalyst carriers, medical care, health care, refractories, and textiles.
Zirconia ceramic processing accuracy
How to choose zirconia ceramic?
The following methods can be used to select high-quality zirconia ceramic components:
Firstly, observe whether the hardness of the zirconia ceramic component meets the standard, as well as its wear resistance, thermal conductivity, chemical stability, and corrosion resistance.
Secondly, the zirconia ceramic component must have good refractory properties because it is a high-temperature resistant ceramic, so it should be able to withstand at least 1000 degrees Celsius.
Thirdly, the zirconia ceramic component must have good chemical stability and high resistance to acid corrosion under high-temperature conditions.
Finally, the density of the product must be high, and it should have high biocompatibility.
