Hot corrosion behavior of the La2(Zr0.7Ce0.3)2O7 ceramic in molten V2O5 and a Na2SO4+V2O5 salt mixture

La2O3 can readily react with V2O5 to form LaVO4, followed by CeO2 interacting with V2O5 to form CeVO4. La2O3 is easier to react with NaVO3 in compared with the reaction between La2Zr2O7 and V2O5. The calculated results are in good agreement with the experimental results.210
