Renewable energy sources are gaining more attention and research in this field is increasing. However, the efficient utilization of the produced energy is of greater importance. In this study, a CaMnO3 structure with perovskite structure was produced using acetate starting materials. Various analyses were conducted to determine the thermoelectric properties of the material. The CaMnO3 structure was successfully obtained as a single phase without the formation of secondary phases.
Renewable energy sources draw attention day by day and studies in this field are increasing. However, in addition to producing energy, the efficient use of the energy produced is of greater importance. Thermoelectric materials come into play at this stage, but the production of materials at the desired level in terms of efficiency is still a problem. In this study, CaMnO3 structure with perovskite structure, which allows the production of many high-tech materials with its variable structure, was produced with acetate starting materials. Specific phase formation by X-ray diffraction analysis of the obtained material, Differential thermal analysis and thermogravimetric analysis endothermic, exothermic, and mass change in the material with temperature, Fourier Transform Infrared Spectroscopy between Ca and Mn bonding, scanning electron microscopy and transmission electron microscopy) single-phase CaMnO3 investigations, Laser flash analysis and Electrical Resistance Measurement Systems (SEM ULvac) analyzes were used to determine the thermoelectric properties. The CaMnO3 structure was obtained as a single phase without the formation of secondary phases with the initial precursors without using different dopants.
