Abstract
The present research demonstrates the synthesis and characterization of Ca0.9Er0.1MnO3 perovskite powder using the sucrose nitrate procedure (SNP) technique. The following substances were used to obtain this complex perovskite: sucrose C12H22O11, which has a dual role (complexant and fuel), and metal nitrates were used as oxidants - calcium nitrate tetrahydrate Ca(NO3)2×4H2O, manganese(II) nitrate hydrate Mn(NO3)2×H2O, erbium(III) nitrate pentahydrate Er(NO3)3×5H2O. Nanopowder was prepared by combining metal nitrates in their respective stoichiometric ratios. The synthesized Ca0.9Er0.1MnO3 powder was calcined in a temperature range of 800–1000 °C for a period of 15 min. The effects of calcination were characterized through different experimental techniques (differential thermal analysis (DTA), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Field emission scanning electron microscopy (FESEM), and inductively coupled plasma (ICP))
