Abstract

Namen diplomskega dela je optimiziranje reakcijskih parametrov (volumen oleinske kisline, čas sinteze) pri hidrotermalni sintezi BaFe12O19 z namenom, doseči čim manjšo velikost nanodelcev. Sintetizirane delce smo karakterizirali s termogravimetrično analizo (TGA) in ocenili velikost delcev s pomočjo rentgenske praškovne difrakcije (XRD). Velikost delcev smo izračunali s pomočjo Sherrerjeve enačbe. Rezultati so pokazali, da dodatek oleinske kisline med hidrotermalno sintezo in krajšanje časa sinteze tr na splošno zavirata rast velikih delcev BaFe12O19.

Secondary title:	Hydrothermal synthesis of barium hexaferrite in the presence of oleic acid
Secondary abstract:	The aim of work was to optimize reaction parameters (volume of oleic acid, synthesis time) during the hydrothermal synthesis of BaFe12O19 in order to obtain small final particle size of BaFe12O19 nanoparticles. Synthesized particles were characterized with thermogravimetric analysis (TGA) and the size of particles was estimated with X-ray powder diffraction (XRD). The size of nanoparticles was calculated with Sherrer's equation. The results showed that addition of oleic acid and decreasing of synthesis time tr reduce the growth of nanoparticles BaFe12O19.
