Evaluation of carbonate precursors in manganite coprecipitation synthesis by Fourier transform infrared (FTIR) spectroscopy
The simple perovskite oxides, manganites, are nowadays subject of extensive research because of their electrical, magnetic and photocatalytic properties. In this paper, manganites described with general formula A1-xSrxMnO3 (A = Ca, Ba, La) were prepared by the coprecipitation method. Precursors and calcined powders were analyzed by Fourier transform infrared (FTIR) spectroscopy and crystallization was studied by X-ray diffraction. In all systems, successfully doped manganites were obtained by coprecipitation. Positions and shapes of carbonate bands in carbonate precursors FTIR spectra were shown to be useful for screening successful syntheses of doped manganites, particularly in Ca1-xSrxMnO3 and La1-xSrxMnO3 systems.
