dc.description.abstractovom radu prikazani su eksperimentalni rezultati ispitivanja procesa oksidacije bakar(I)-sulfida kiseonikom u temperaturnom intervalu 473-773 K i vremenu 5-120 min. Određen je stepen oksidacije bakar(I)-sulfida do bakar(I)-oksida i bakar(II)-sulfata u zavisnosti od temperature i vremena. Termodinamička analiza obuhvatila je proračun Gibsove enrgije za izabrane hemijske reakcije i analizu dijagrama stabilnosti log pSO2 - log pO2 sistema Cu-S-O, na osnovu čega je definisan hemizam procesa oksidacije bakar(I)-sulfida kiseonikom.sr
dc.description.abstractThis paper presents experimental results of the investigation on the oxidation process of copper(I)-sulphide by oxygen in the temperature range of 473-773K and during various time intervals 5-120 min. The quantities of copper(I)-sulphide oxidized to copper(I)-oxide and copper(II)-sulphate at different temperatures were determined. Thermodynamic analysis included calculation of standard Gibbs energy change for supposed chemical reactions and analysis of isothermal log pSO2 - log pO2 stability diagrams in system Cu-S-O. On the basis of experimental data and thermodynamic calculations the chemistry of copper(I)-sulphide oxidation by oxygen was defined.en
