AB - The structural change and the electrical conductivity with Sr content in La1 − xSrxMn0.8Cu0.2O3 (LSMCu) were studied. La0.8Sr0.2MnO3 (LSM) and La1 − xSrxMn0.8Cu0.2O3 (0.1 ≤ x ≤ 0.4) were synthesized by EDTA citric complexing process (ECCP). A decrease in the lattice parameters and lattice volumes was observed with increase of Sr content, and these results were attributed to the increasing Mn4+ ions and Cu3+ ions in B-site. The electrical conductivity measured from 500oC to 1000oC was increased with increase of Sr content in the 0.1 ≤ x ≤ 0.3 composition range, and it was 172.6 S/cm (at 750oC) and 177.7 S/cm (at 950oC, the maximum value) in x = 0.3. The electrical conductivity was decreased in x = 0.4because of the presence of the second phase in the grain boundaries. The lattice volume was contracted by increase of Mn4+ ions and Cu3+ ions in B-site according to increase of Sr content and the electrical conductivity was increased with increase of charge carriers which were involved in the hopping mechanism.
