Product Description
Introduction of Yttria Stabilized Zirconia
Thermal expansion coefficients of yttria stabilized zirconia(YSZ) with the Y2O3 content of 3, 6, 8 and 10 mol% were measured using a push-rod type dilatometer in the temperature range from 103 to 876 K. The thermal expansion coefficient of YSZ decreased with the increase of the Y2O3 content. The thermal expansion coefficient of YSZ was theoretically estimated for the various Y2O3 contents using the values of isochoric heat capacity, molar volume, isothermal bulk modulus and the Gruneisen constant in a good agreement with the experimental results. Among the physical properties, the bulk modulus is considered to be mainly responsible for decreasing the thermal expansion coefficient of YSZ with the increase of Y2O3 content. The doping effect of Y2O3 in YSZ on the thermal expansion coefficient was discussed using a molecular dynamics simulation.
