Effect of rare earths (RE) in the rare earth copper oxides, RE2CuO4 (RE = La, Pr, Nd, Sm, Gd) and RE2Cu2O5 (RE = Dy, Ho, Er, Yb, Y), on the carbon oxidation was investigated by the DSC (differential scanning calorimetry) measurement. Orthorhombic La2CuO4 and tetragonal RE2CuO4 (RE = Pr–Sm) prepared at 800°C showed higher carbon oxidation activity compared with CuO processed at the same temperature, whereas activity of the orthorhombic RE2Cu2O5 (RE = Dy–Yb, Y) prepared at 1000°C was lower than that of CuO processed at the same temperature.
