PURPOSE:To provide a method for sintering a lanthanum chromite doped with an alkaline earth metal in a high density. CONSTITUTION:When a lanthanum chromite La(1-x)MxCrO3 (M is Ca or Sr) or LaCr(1-x)MgxO3 doped with an alkaline earth metal is sintered, calcium chromate CaCrO4 or CaCrO4.2H2O is added as a sintering auxiliary. |
