Effect of Coupled Conditions of Thermal Cycle and Dump Environment on Microstructure of 5mol% Yttria Stabilized Zirconia


Article Preview

In some applications such as automotive oxygen sensor, 5mol% Y2O3stabilized zirconia (5YSZ) is generally used because it has both excellent ionic conductivity and mechanical properties. the automotive oxygen sensor would experience a cyclic change from high temperature (engine running) environment to the lowtemperature damp environment (in the tail pipe when vehicle stops). The microstructures change with coupled conditions of thermal cycle and dump environment in the 5mol%Y2O3–ZrO2 (5YSZ) system was examined by XRD,Raman spectroscopy and scanning electron microscopy (SEM) in this paper.
