Abstract
This work presents step by step procedure for synthesis of calcium manganese oxide (CaMnO3) prepared by co-precipitation method starting with stoichiometric amounts of calcium nitrate tetrahydrate and manganese nitrate tetrahydrate as precursors. The resulting powders of CaMnO3 are characterized for their crystallographic and spectroscopic properties. The X-ray diffraction patterns reveal formation of CaMnO3 consistent with the corresponding JCPDS. The Fourier transform infrared spectra represents the presence of Ca-O and Mn-O bond in the synthesized powders. The optical band gap of the samples is evaluated as 4.06–4.14 eV by studying the UV-Visible spectrum. The field emission scanning electron microscope images reveal irregular feature sizes with some nearly spherical particles in the synthesized samples. The currently prepared highly pure CaMnO3 attained can be consolidated into hot-pressed ceramics for measuring their electronic and thermoelectric properties to study their thermoelectric performance
