Abstract
Cilj ovog diplomskog rada bio je sintetizirati kalcij-manganitni prah za nanošenje tankih prevlaka iz suspenzije. Kalcijev manganit sintetiziran je pomoću slijedećih metodama sinteze iz otopine: Pechinijeva metoda, limunska metoda i metoda koprecipitacije. Dobiveni uzorci žareni su na temperaturama 600 – 900 °C radi dobivanja kristalnog kalcijevog manganita. Sintetizirani uzorci karakterizirani su rendgenskom difrakcijskom analizom, infracrvenom spektroskopijskom analizom, kombiniranom diferencijalnom pretražnom kalorimetrijom i termogravimetrijskom analizom, te elektronskom mikroskopijom. Za pripremu prevlaka korištena je metoda nanošenja iz suspenzije keramičkog praha. Za pripremu suspenzija korišteni su uzorci žareni na 900 °C. Suspenzije su pripremljene u etanolu, a da bi se postiglo ravnomjerno raspršenje čestica praha bez aglomerata, pripremljena suspenzija bila je u ultrazvučnoj kupelji. Analizom dobivenih rezultata utvrđeno je da se kao najbolja metoda sinteze kalcijeva manganita pokazala jednostavna metoda koprecipitacije. Pripremljene suspenzije tako sintetiziranog praha daju prevlake koje sadrže čestice odgovarajuće veličine bez prisutnosti velikih aglomerata.
Abstract (english)
The aim of this graduate thesis was to synthesize calcium manganite powder for the application of thin coatings from the suspension. Calcium manganite was synthesized by following methods of synthesis from the solution: Pechini's method, citric method and copreciptition method. The obtained samples were calcined at 600 – 900 °C to obtain crystalline calcium manganite. The synthesized samples were characterized by X-ray diffraction analysis, infrared spectroscopy, combined differential scanning calorimetry and thermogravimetric analysis, and electron microscopy. The coatings were prepared from the suspension of ceramic powder, previously calcined at 900 °C. The suspensions were prepared in ethanol and in order to achieve uniform dispersion of agglomerated powder particles, the prepared suspension was treated in the ultrasonic bath. Analysis of the obtained results showed that the best method for the synthesis of calcium manganite, was simple coprecipitation method. The prepared suspensions of that synthesized powder give coatings containing particles of the corresponding size without the presence of large agglomerates.
