| Tartalmi kivonat: | Perovskite LaMnO3 and related materials are technologically important for many possible applications due to their unique physical and chemical properties. It is well known that the properties of the materials depend on their synthesis processes, as have been already shown in the literature for a large class of materials [1, 2]. In this work, lanthanum manganite perovskite type materials prepared by ultrasonically method with immersed sonotrode in the reaction medium and sol-gel method, followed by heat treatment at 600°C, 6 h are reported. The asprepared samples were characterized by X-ray diffraction (XRD), thermal gravimetric analysis (TGA), surface area analysis (BET), scanning / transmission electron microscopy (SEM /HRTEM/EDX), and FT-IR spectroscopy. X-ray diffraction indicates that the synthesized materials are well crystallized, with perovskite structure and without any secondary phases. |
