Abstract
Mehanokemijska sinteza je u današnje vrijeme veoma istraživana metoda zbog kraćeg vremena reakcija i mogućnosti korištenja slabo topljivih reaktanata. Uporaba otapala svedena je na minimum što doprinosi zaštiti okoliša. U ovom diplomskom radu sintetizirane su nanočestice složenih metalnih oksida kalcija i željeza metodom visokoenergetskog mljevenja unutar planetarnog kugličnog mlina. Dobiveni spojevi okarakterizirani su termogravimetrijskom analizom (TGA), infracrvenom spektroskopijom (FT-IR) i cikličkom voltametrijom (CV). Nadalje, promjenom različitih parametara mljevenja ispitani su uvjeti potrebni za nastajanje različitih struktura mješanih metalnih oksida kalcija i željeza. Također, opisan je i metodički dio na temu ‘’Zemnoalkalijski metali’’ za 3. razred gimnazije koji sadrži pisanu pripremu za nastavni sat i radni listić. Predviđeno je frontalno predavanje koje završava zajedničkim ponavljanjem naučenog gradiva kroz pitanja na radnom listiću.
Abstract (english)
Mehanochemical synthesis is nowadays a highly explored method for a shorter reaction time and the ability to use poorly soluble reactants. The use of solvents is reduced to a minimum that contributes to the protection of the environment. In this graduate thesis, nanoparticles of complex metal oxide of calcium and iron are synthesized by the method of high-energy grinding within a planetary ball mill. The obtained compounds are characterized by thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FT-IR) and cyclic voltammetry (CV) method. Furthermore, by changing the various parameters of milling, the conditions necessary for the formation of different structures of calcium and iron mixed metal oxides are examined. This thesis also contains a part with teaching methods on high school level including printed preparation for lesson "Earth Alkaline Metals" and corresponding working papers. A frontal lecture is envisaged that ends with a common repetition of the subject matter through questions on working paper.
