Abstract
Cilj ovog rada bio je reakcijom u čvrstom stanju sintetizirati stroncijev manganit (SrMnO3), lanatanov manganit (LaMnO3) i barijev manganit (BaMnO3) pomoću dva strukturno različita manganova (IV) oksida (MnO2) te tako ispitati utjecaj reaktanata na sintezu. Uzorci dobiveni ručnom homogenizacijom žareni su na temperaturama od 1000 i 1200 °C. Za određivanje sastava i strukture sintetiziranih spojeva korištene su rendgenska difrakcijska analiza (XRD) i infracrvena spektroskopija s Fourierovim transformacijama (FTIR). Iste tehnike analize primijenjene su i na dva različita MnO2 čime je utvrđeno da jedan kristalizira u heksagonskom, a drugi u tetragonskom kristalnom sustavu. Dobiveni rezultati pokazuju da su sintezom navedenih spojeva iz heksagonskog MnO2 dobivene čišće manganitne faze.
Abstract (english)
The purpose of this work was to synthesize compounds of strontium manganite (SrMnO3), lanthanum manganite (LaMnO3), and barium manganite (BaMnO3) by solid-state reaction using two structurally distinct manganese (IV) oxides and therefore examine the influence of reactants on the synthesis. The obtained products were calcined at temperatures of 1000 and 1200 °C. X-ray diffraction analysis (XRD) and Fourier transform infrared spectroscopy (FTIR) were used to determine the composition and structure of the synthesized compounds. The same analysis techniques were applied to two different MnO2, with the one being found to crystallize in the hexagonal and the other in the tetragonal crystal system. The obtained results show that the synthesis of these compounds using hexagonal MnO2 gave purer phases of manganite.
