摘要: Doped lanthanum chromites are investigated as ceramic interconnect materials to be used in high-temperature solid oxide fuel cells (SOFCs). This paper deals with the preparation of LaCr1−xMxO3 (M = Ni, Cu, x 0 − 0.2) from complex precursors isolated La(NO3)3-Cr(NO3)3-M(NO3)2-urea system. The were characterized by atomic absorption spectrometry, electronic, and FT-IR spectra, well as, thermal analysis. chromites, Cu) prepared calcining corresponding urea-based at 1000-1200°C for 2 h. mixed-oxide samples X-ray diffraction (XRD), Scanning electron-microscopy-energy-dispersive analysis (SEM-EDX), electrical conductivity, magnetic measurements.
