Zirconia ceramics is the strongest and toughest material among advanced ceramics.
Zirconia (ZrO2) has a monoclinic crystal structure at room temperatures, but transforms to cubic and tetragonal structures at elevated temperatures. This transition can result in the development of stresses during cooling which negatively impact the strength of the material.
Properties of Yttria Stabilized Zirconia ceramics: The working temperature is up to 2100 ℃; high density, low thermal conductivity; chemically inert; anti-metal melting; ion conductivity; wear resistance, high hardness, high fracture toughness.
Zirconia Ceramic performance parameters:
Chemical composition: ZRO2≥94.5%
Density: 6g/cm3
Sintering temperature: 1550~2600°C
Breakdown voltage strength: 15 kV/mm
Water absorption: <0.01%
Compressive strength: 5000 MPa
Hardness: ≥88(Hra)
Volume resistance: >1012 cm
Bending strength: 1100 MPa
Thermal expansion coefficient: 6.9~10 x10^(-6)/k
Thermal conductivity: 2.5 W/m-k
