ZRO2 Zirconia Ceramic Sheet Substrate

Product Description
Zirconia ceramic Sheets are characterized by high toughness, high bending strength, high hardness and high wear resistance. 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.

Ceramic material composition:

– – 95%–99.99% Alumina (Al2O3)
– – Silicon Carbide · Silicon Nitride
– – TTZ: Magnesia partially stabilized Zirconia (ZrO2)
– – YTZP: Yttria partially 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)
