Abstract
U ovom radu istraživane su dvije metode sinteze stroncijeva manganita i lantanova manganita dopiranog stroncijem. Stroncijev manganit sintetiziran je limunskim postupkom i koprecipitacijom, a kao izvor metalnih kationa korišteni su stroncijev karbonat i manganov (II) nitrat tetrahidrat. Dopiranje lantanova manganita stroncijem provedeno je koprecipitacijom iz otopine stroncijeva karbonata, manganova (II) nitrata tetrahidrata i lantanova (III) nitrata heksahidrata. Za određivanje sastava i strukture sintetiziranih prahova korištene su tehnike rendgenske difrakcije praha, infracrvene spektroskopije i simultane termogravimetrijske analize i diferencijalne pretražne kalorimetrije. Čista faza stroncijeva manganita dobivena je limunskim postupkom uz omjer metala i limunske kiseline 0,5:1 i koprecipitacijom uz dodavanje taložnog reagensa kap po kap. Koprecipitacijski uvjeti korišteni u ovom radu nisu prikladni za dopiranje lantanova manganita stroncijem.
Abstract (english)
This master's thesis presents a study of two synthesis routes for strontium manganite and strontium doped lanthanum manganite. Strontium manganite was synthesized by the citric acid auto-combustion method and by coprecipitation, using strontium carbonate and manganese (II) nitrate tetrahydrate as a source of metal cations. Lanthanum manganite was doped with strontium by coprecipitation from strontium carbonate, manganese (II) nitrate tetrahydrate and lanthanum (III) nitrate hexahydrate solution. X-ray diffraction, infrared spectroscopy and simultaneous thermogravimetric anaylsis and differential scanning calorimetry were used to determine the composition and structure of the synthesized powders. The pure phase of strontium manganite was obtained by the citric acid method with a metal to citric acid ratio of 0,5:1 and by coprecipitation with the addition of a precipitating reagent dropwise. The coprecipitation conditions used in this thesis are not suitable for the doping of lanthanum manganite with strontium.
