Abstract

Namen našega dela je bil poskušati sintetizirati nekatere izmed halkogenidov prehodnih kovin 4. periode (MxEy; M = Zn, Ni, Co; E = S, Se, Te). V ta namen smo poskušali izvesti sinteze s pomočjo mehanokemijskih metod. Uporabljali smo visokoenergijski kroglični mlin SPEX 8000M. Vse sintetizirane produkte po mletju smo analizirali z rentgensko praškovno difrakcijo (XRD), nekatere pa tudi s termogravimetrično analizo (TGA). Namen študije je bil spoznavanje mehanokemijskih metod, rentgenske praškovne difrakcije in termogravimetrične analize. Diplomsko delo prikazuje opis vseh sintez, ki smo jih izvedli in rezultate teh sintez. Na splošno rezultati kažejo, da je uporaba mehanokemijskih metod za sintezo halkogenidov prehodnih kovin 4. periode učinkovita.

Secondary abstract:	The purpose of our work was trying to synthesize some of the transitional metal chalcogenides of 4. period (MxEy; M = Zn, Ni, Co; E = S, Se, Te). The goal was to perform the synthesis by using mechanochemical methods. We used high energy ball mill SPEX 8000M. All synthesized products after milling were analyzed using X-ray powder diffraction (XRD), and some with thermogravimetric analysis (TGA). The purpose of the study was to get acquainted with mechanochemical methods, X-ray powder diffraction and thermogravimetric analysis. This diploma thesis shows the description of all the performed syntheses including the results of those performed syntheses. In general, the results show that mechanochemical methods are effective for the synthesis of the transitional metal chalcogenides of 4. period.
