Almost four decades ago dr.sc. Svetozar Musić introduced at the Rudjer Bošković Institute, Zagreb,  the research in chemistry of metal oxides. This research started with the preparation of wo interconnected cupolas of a-Fe2O3 precipitated from dense a-FeOOH suspension with added ammonium amidosulfonate (M. Žic, M. Ristić, S. Musić, J. Mol. Struct. 924-926 (2009) 235)metal oxide carriers labelled with cyclotron radioisotopes for applications in nuclear medicine and it was followed with the investigation of the hydrolytic processes and precipitation of iron oxides. With time a research group in chemistry of metal oxides was formed which started a systematic investigation of other metal oxide systems such as, ZrO2, TiO2, ZnO, Ga2O3, Nb2O5, WO3 etc. The aim of these investigations was to ascertain the relationship between the synthesis route and specific properties of metal oxide particles. The kinetics and mechanisms of the precipitation of metal oxides were investigated. The formation of solid solutions in different metal oxide systems was also determined. The formation and properties of ferrites with spinel-, perovskite- or garnet-type structure were investigated. In all these investigations a particular attention was focused to the formation of nanostructured metal oxides. The application of X-ray powder diffraction in combination with other techniques (Mossbauer, FT-IR, Raman, electron microscopy) made possible to study the structure, phase composition, phase diagrams, chemical bonds, as well as the size and morphology of the particles of metal oxides (e.g. J.Mater.Sci. 24(1989)2722; Mater.Letters 23(1995)139; J.Mater.Sci. 31(1996)4067; J.Alloys Comp. 241(1996)10; Thermochim.Acta 303(1997)31; Croat.Chem.Acta 71(1998)789; J.Non Cryst.Solids 303(2002)270; J.Alloys Comp. 398(2005)188; 429(2007)242, J. Mol. Struct. 924-926(2009)243).
