Mechanical alloying synthesis and comprehensive characterization of SmCoO3 perovskite through XRD, XRF, DSC, and UVVis absorbance

In this study, a nanostructured perovskite SmCoO3 material was successfully synthesized at ambient temperature using the mechanical alloying (MA) technique. A powdered mixture of samarium and pure metallic cobalt (Co) precursors was subjected to 24 h of milling to achieve the intended sample. The phase transformations induced by high-energy milling were investigated through ex situ X-Ray Diffraction (XRD) measurements and analyzed using the Rietveld method. Some properties of SmCoO3 were examined using techniques such as Differential Scanning Calorimetry (DSC), heat treatment, XRF (X-Ray Fluorescence), and UVVis absorbance. These comprehensive characterizations provide valuable insights into the synthesis and properties of nanostructured SmCoO3 perovskite, facilitating its potential applications in various fields.
