In this work the advantage of the use of the microwave technology was exploited for the preparation of perovskite ceramics. Microwave-assisted hydrothermal method has been applied to the preparation of strontium-doped lanthanum manganites with different stoichiometric ratio of the three oxides, La1-x SrxMnO3 (x = 0.3, 0.5, 0.6). In particular, pure black narrow dispersed crystallites of La0.5Sr0.5MnO3 of 0.68?0.18 ?m were prepared in only 45 minutes at 240?C and a KOH concentration of 21 M. The complete chemical, mineralogical and microstructural characterization of the powders reveal the same structural properties of the perovskite powders previously synthesised by ceramic and conventional hydrothermal routes. .

Post Synthesis

A microwave-assisted solution-phase approach has been applied for the synthesis ofzinc oxide microstructures. Toe synthesis procedure was carried out by using the reagents: Zinc ni trate and Methenamine, at stoichiometric ratio. Analysis by means ofX-ray Diffraction (XRD) shows a crystalline phase in hexagonal wurtzite arrangement for ZnO. The presence ofmicrostar shaped zinc oxide (2-3μm) with nanorods,f50nm) arranged has been confirmed from High Resolution Scanning Electron Microscopy (HRSEM). The formation of nanorods was confirmed by Transmission Electron Microscopy. In Raman spectroscopy a red shift was detected in the microstructures compared with ZnO bulk. High crystalline materials without additional post-synthesis treatrnent were found.
