Product Description

Product Description

 

Do you know zirconia ceramics? Do you know its application? Some brief introductions of zirconia ceramics are for your reference. 1. Zirconia ceramics have high fracture toughness, excellent wear resistance, strong bending resistance, and good thermal insulation. It has almost the same thermal expansion capacity as steel. So we can use it in structural ceramics. 2. The high-temperature performance of zirconia ceramic is excellent, so it can use to produce Heating element and refractory materials. 3. Zirconia ceramics have good electrical sensitivity so that it can be used to make oxygen sensors and solid oxides. 4. Besides, zirconia ceramic products include valve trim, precision balls, nozzles, tool and pump liners, plungers, blades, and so on.Zirconia ceramics have many advantages and characteristics, and there are many applications for it. If you are interested, just contact us.

5.Zirconia ceramics have a dimensional hardness of 11.5GPa, a density of 6.0g/cm3 and a compressive strength of 2100MPa. Zirconia ceramics are widely used as ductile ceramics with fracture toughness up to 8.0 mpAM1/2.

Applications: machinery, optical fiber, cutting tools, food, chemical, aerospace

Ceramic material composition:
- - 95%--99.99% Alumina (Al2O3)
- - Silicon Carbide · Silicon Nitride
- - TTZ: Magnesia partially stabilized Zirconia (ZrO2)
- - YTZP: Yttria partially stabilized Zirconia (ZrO2)
- - ZDY: Yttria fully stabilized Zirconia (ZrO2)

Properties of Zirconium Oxide (ZrO2)
* High thermal expansion (α=11 x 10-6/K, similar to some types of steel)
* Excellent thermal insulation/low thermal conductivity (2.5 to 3 W/mK)
* Very high resistance to crack propagation, high fracture toughness (6.5 to 8 MPam1/2)
* Ability to conduct oxygen ions (used for the measurement of oxygen partial pressures in lambda probes)
