| 中文摘要 | (La0.75Sr0.25)0.95MnO3±δ (LSM) powders have been synthesized via a Pechini route. The prepared powders were characterized by XRD, SEM, XRF, BET and particle size distribution (PSD) analysis. It is shown that the morphology and structure of the oxide particles are significantly dependent on the preparation conditions such as the sort of surfactant andpHvalue of the starting solution. High purity, single phase,homogeneous, nanocrystalline LSMpowders with slight aggregationwere obtained using citric acid as complexing agent, ethylene glycol as surfactant and pH 1. The conductivity of the sintered LSM sample prepared from this nanocrystalline powderswas mensurated about 200 S cm−1 in air at 600–1000 ℃. The impedance spectra of symmetric cells LSM–YSZ/YSZ/LSM–YSZ were measured in air and open circuit voltage condition. The optimal polarization resistance (Rp) of 0.175Ωcm2 at 750℃ and 0.07Ωcm2 at 800℃ was obtained in the sample with LSM to YSZ weight ratio of 49:51. |
