چکیده انگلیسی
The hot corrosion behaviors of Sr(Y0.05Yb0.05Zr0.9)O2.95 (SYYZ) ceramic were investigated in Na2SO4, V2O5, and Na2SO4 + V2O5 salts mixture, respectively. Na2SO4 did not react with SYYZ ceramic at 900, 950 and 1000 °C. m-ZrO2, YVO4 and YbVO4 were the main corrosion products on the SYYZ ceramic surface in V2O5 at 800 and 900 °C, whereas Sr3V2O8 and t-ZrO2 appeared at 1000 °C. In Na2SO4 + V2O5 salts mixture, the corrosion products were Sr3V2O8 and t-ZrO2 at 800 and 900 °C on the SYYZ ceramic surface, however, a new phase of SrZrO3 developed at 1000 °C. The phase transformation and chemical interaction are the primary corrosion mechanisms for degradation of SYYZ ceramic.
