Thermal analysis and prediction of phase equilibria in ternary Pb-Zn-Ag system

Journal of Mining and Metallurgy Section B Metallurgy (2011)

Dragana Živković Duško Minić Dragan Manasijević Jaroslav Šesták Živan Živković

Ternary Pb-Zn-Ag system is typical for some physicochemical processes going on in refining phase in the extractive metallurgy of lead. Therefore, investigation of mentioned system is important from both theoretical and practical research of the phenomena occurring during the lead desilverizing process. The results of experimental investigation using differential thermal analysis (DTA) and thermodynamic calculation of phase equilibria in Pb-Zn-Ag system according to CALPHAD method, in the sections with Zn:Ag mass ratio equal to 90:10, 70:30 and 50:50, are presented in this paper.

Correction: Nanomaterials environmental risks and recycling: Actual issues (2014, vol. 7, p. 1)

Reciklaza i odrzivi razvoj (2016)

Dragana Živković Ljubiša Balanović Aleksandra Mitovski Nadežda Talijan Nada Štrbac

Editorial board of the 'Recycling and Sustainable Development' Journal in agreement with the authors of the article titled 'Nanomaterials environmental risks and recycling - actual issues' (D. Zivkovic, Lj. Balanović, A. Mitovski, N. Talijan, N. Strbac , M. Sokić, D. Manasijević, D. Minić, V. Ćosović), which was published in this journal vol. 7 in 2014 (p. 1-8), made the decision to do correction of article because of a perceived serious oversights (based on check out by CEON). Oversight is reflected in inadequate citing a reference, or omission of reference from which the text used by individual states, as well as the duplication of certain references. The necessary correction refers to the parts of the article which reference source is not adequately specified and updates the list of references, in accordance with prescribed procedure.

Experimental Determination fo Ga Activity in Liquid Ga-Sb-Tl Alloys by EMF Method

Diffusion and defect data, solid state data. Part B, Solid state phenomena/Solid state phenomena (2007)

Iwao Katayama Yusuke Sendai Dragana Živković Dragan Manasijević Živan Živković

EMF of galvanic cell with zirconia –based solid electrolytes was measured to determine the activity of Ga in liquid Ga-Sb-Tl alloys between 946 and 1233 K along the tree pseudobinary lines of Ga-(Sb/Tl), (xSb/xTl = 1/3, 1/1 and 3/1) The cell used was: Ga,Ga2O3|(ZrO2)0.92(Y2O3) 0.08|Ga-Sb-Tl, Ga2O3. The activity of Ga (aGa ) was derived by :-3EF = RT ln aGa , where E is cell potential, F is Faraday’s constant, R is gas constant and T is cell temperature. The activity of Ga shows slight negative deviations from ideality in the section with positive deviation from ideality in the whole composition range. The activity of gallium shows slight negative deviations from Raoult’s law in the section with xSb/xTl = 3/1, moderately positive deviations in xSb/xTl =1/1 section and large positive deviations in xSb/xTl =1/3 section.

Experimental and thermodynamic description of ternary Bi-Cu-Ga system

Journal of Mining and Metallurgy Section B Metallurgy (2017)

Duško Minić Yong Du Milena Premović Dragan Manasijević N. Talijan

Phase diagram of the Bi-Cu-Ga ternary system has been investigated experimentally with 27 alloys and analytically by using a Calphad method. Thirteen annealed alloys at 200?C were investigated by using scanning electron microscopy (SEM) with energy dispersive spectrometry (EDS), and X-ray powder diffraction (XRD) methods. Temperatures of phase transformation were determined with 14 alloys which are lying along three vertical sections Bi-Cu0.5Ga0.5, Cu-Bi0.5Ga0.5 and Ga-Bi0.5Cu0.5 by using differential thermal analysis (DTA). Based on the experimental result and by using Calphad method, ternary phase diagrams were constructed with a new description of liquidus phase. Calculated phase diagram and experimentally obtained results are in good agreement. Liquidus projection and invariant reaction were calculated by using new thermodynamic parameters for liquidus phase.

The results of thermodynamic study and characterization of some alloys in Ga-Sn-Zn system are presented in this work. Thermodynamic study was conducted experimentally - using Oelsen calorimetry method and analytically - according to Redlich-Kister-Muggianu model and compared with available literature data. Characterization of alloys was done using differential thermal analysis and scanning electron microscopy, and obtained results were used in phase diagram defining of investigated section in Ga-Sn-Zn system.

Calculation of activities in some gallium-based systems with a miscibility gap

Journal of the Serbian Chemical Society (2003)

Dragan Manasijević Dragana Živković Iwao Katayama Živan Živković

The calculations of thermodynamic properties in some gallium-based systems with a miscibility gap ? Ga?Tl, Ga?Hg and Ga?Pb are presented in this paper. The determination of the gallium activities in the mentioned liquid alloys was based on their known phase diagrams using the Zhang-Chou method for calculating activities from phase diagrams involving two liquid or solid coexisting phases. The activities of gallium in Ga?Tl, Ga?Hg and Ga?Pb system were calculated in the 973?1273 K, 573?873 K and 1000?1100 K temperature ranges, respectively. The activities of the other component in all the investigated systems were obtained by the Gibbs-Duhem equation. The results of the calculations are compared with literature data.

Thermal and structural characteristics of a eutectic Au-Ge alloy

Materials Testing (2017)

Dragana Živković Diana Ćubela Dragan Manasijević Ljubiša Balanović Almaida Gigović-Gekić

Abstract The Au-Ge alloy is useful for bonding applications in microelectronic and optoelectronic packages. Also, recent investigations show that Au-Ge system could present a lead-free solder candidate. The results of characterization of the eutectic alloy from binary Au-Ge system are presented in this paper. Experimental research was done using thermal analysis (differential thermal analysis, DTA) and structural investigation by light optic microscopy (LOM) and scanning electron microscopy with EDS (SEM-EDS). The eutectic temperature of 359 °C was detected using thermal analysis, while eutectic structure was confirmed using microstructural analysis. Obtained results were compared with recent literature references and good mutual agreement was noticed.
