Abstract

SmYbZr₂O₇ ceramic powders were pressureless-sintered at 1700 °C for 10 h to fabricate dense bulk materials. SmYbZr ₂O₇ exhibited a single phase of defect fluorite-type structure. Hot corrosion tests between SmYbZr₂O₇ and V₂O₅ were carried out in an electric furnace at temperatures of 600-1000 °C for 2 h in air, respectively, and the reaction products were investigated using X-ray diffraction, laser Raman spectroscopy and scanning electron microscopy. The final corrosion products were composed of (Sm,Yb)VO₄ and ZrV₂O₇ or m-ZrO₂, depending upon the reaction temperature. Hot corrosion mechanisms were further discussed based on the thermal instability of ZrV₂O₇ at elevated temperatures.
