Zirconia(ZrO?) Ceramic
Featured Product from Xiamen Unipretec Ceramic Technology Co., Ltd.
Zirconia (ZrO?) material is known as one of the hardest ceramics. It also has properties of high thermal expansion, low thermal conductivity, superior resistance to abrasion/wear and corrosion, as well as high temperature resistance. Due to its excellent fracture toughness, zirconium oxide ceramic performs not that brittle as aluminum oxide ceramic. Its outstanding performance in resisting crack propagation along with high thermal expansion make zirconia work excellent in joining ceramic and metals, prominently in applications like ceramic plunger and ceramic piston pump.
ZrO? Ceramics Material Advantages:
- Using temperature up to 800 °C
- Low thermal conductivity
- Chemical inertness
- Resistance to molten metals
- Wear resistance
- High fracture toughness
- High hardness
There’re several types of zirconia materials, typical types are as follows:
Yttria (Y2O3) Partially Stabilized Zirconia – YTZP High stress strength and toughness, good chemical inertness, superior mechanical properties, electrical insulating, using temperature below 800°C, fine surface finish, the most commonly used zirconia material, typical applications such as zircoina piston, sleeve, bushing, washer, bearings, cutting blades, etc.
Ceria Stabilized Zirconia (CSZ) This material is usually used for grinding ball. High density 6.20g/cm³, low wear, high grinding efficiency, generally used for paint and oil industry, cosmetic , magnetic material, mineral industry, etc.
Zirconia-Toughened Alumina (ZTA) Provide greater strength and higher toughness than high alumina material. It’s a nice material choice for wear applications like ceramic pump components.
ZrO2 Zirconia Ceramic Applications:
Valve ball and seat components
High density ball grinding media
Plungers for waterjet intensifier
Frac plug buttons
Pump seals and shaft bearings
Pump piston and plunger
Weld Guide Pins
Utility Knife Blades
