Synthesis and Structural Studies of Perovskite-Ytterbium Manganate and Spinel-Cobalt Chromite Nanomaterials

This study investigates the synthesis and structural characterization of the polycrystalline nanocomposite material YbMnO-CoCrO.The synthesis was performed using the sol-gel and Pechini methods.X-ray diffraction analysis was used to determine the phase composition, revealing the presence of perovskite-type ytterbium manganate (YbMnO) and spinel-type cobalt chromite (CoCrO).Data analysis was conducted using the PDXL program, confirming that the nanocomposite is a two-phase system consisting of orthorhombic perovskite and cubic spinel phases.Morphological analysis was carried out using scanning electron microscopy and a high-resolution transmission electron microscopy to respectively confirm the elemental composition and provided average particle size measurements and their distribtion.The particle sizes were determined to be 215-525 nm for YbMnO and 2.11-3.19m for CoCrO.Additionally, 3D surface profiles and nanomaterial growth measurements were obtained using the MP-45030TDI 3D modeling software.
