La2Hf2O7 ceramic was prepared by solution combustion and pressureless sintering method. Hot corrosion behaviors of La2Hf2O7 ceramic against Na2SO4, V2O5 and Na2SO4 + V2O5 (molar ratio = 1:1) were investigated at temperatures of 900–1200°C in air for 4h. Distinct corrosion products and morphology are observed during the isothermal heat-treatment in contact with V2O5 and Na2SO4 + V2O5 molten salts....
