AB  - Alloys with gallium, antimony and zinc, whose elements, metal constituent WEEE (they are specified for mobile phones) are particularly important for developing photoelectron devices, simple reproductive methods of producing p-n structures GaSb, also for production and construction of photo-wave cells in solar panels and they are also processes which develop ceramic semiconductors. In addition, these alloys represent possible substitute for standard lead-tin seam. For the complete definition of the properties of the ternary Ga-Sb-Zn system there were performed many researches of the alloys. The microstructures of the alloys were investigated by usage of SEM with EDS and optic microscopy. By usage of CALPHAD method there was detected the isothermal cross-section at 25 degrees C. The GaSb has similarities in the properties and behaviour with GaAs, and it is a potential material for the construction of the p-n diode, the photo-wave and thermo-photo-wave cells in solar panels and LCDs. Newly developed materials have been recommended as an adequate replacement for lead and arsenic, which are very dangerous and harmful metals.

AB  - In this paper, we have analyzed parts of printed circuit board (PCB) and liquid crystal display (LCD) screens of mobile phones and computers, quantitative and qualitative chemical compositions of individual components, and complete PCBs were determined. Differential thermal analysis (DTA) and differential scanning calorimetry (DSC) methods were used to determine the temperatures of phase transformations, whereas qualitative and quantitative compositions of the samples were determined by X-ray fluorescence spectrometry (XRF), inductively coupled plasma optical emission spectrometry (ICP-OES), and scanning electron microscopy (SEM)-energy dispersive X-ray spectrometry (EDS) analyses. The microstructure of samples was studied by optical microscopy. Based on results of the analysis, a procedure for recycling PCBs is proposed. The emphasis was on the effects that can be achieved in the recycling process by extraction of some parts before the melting process. In addition, newly developed materials can be an adequate substitute for some of the dangerous and harmful materials, such as lead and arsenic are proposed, which is in accordance with the European Union (EU) Restriction of the use of certain hazardous substances (RoHS) directive as well as some alternative materials for use in the electronics industry instead of gold and gold alloys.

AB  - The feasibility study of using different kinds of slag as constituents in construction materials is presented in this paper. As possible materials, slag from silicothermic process of magnesium production is used in fresh and granulated form as binder material and aggregate, and slag formed in process of lead-acid batteries recycling is also added into the mixture. The mixtures are prepared and investigated for their chemical, mineralogical and physical-mechanical properties. Granulated or hydrated magnesium slag is proven to be used as aggregate in mortars and light concrete, fresh magnesium slag showed good pozzolanic properties and is used as a sole binder in decorative and thermo-insulation mortars, and the mixture of magnesium and secondary lead slag with 15% of cement added showed better mechanical properties than standard concrete blocks, considering its lower specific gravity TCLP tests conducted for the building material containing secondary lead slag showed that the material meets the standards for safe disposal.

AB  - The impact of airborne pollution by slag from magnesium production was analyzed under different climate conditions. The slag is characterized by X-ray diffraction analysis, scanning electron microscopy, differential thermal analysis and atomic absorption analysis. The dominant phase was the gamma modification of dicalcium silicate (gamma-2CaO SiO2) with significant amounts of perclas (MgO), gehlenite - 2CaO Al2O3 SiO2, akermanite - 2CaO MgO 2SiO(2) and portlandite Ca(OH)(2). The granulometric composition of the slag was within the range of 100 x 10(-3)divided by 0.090 x 10(-3) m. Ad hoc measurements were performed on site in June at 300 and 600 m distance from the slag deposit, which showed high Total Suspended Particles (TSP) concentrations. Imputing the results of an experimental investigation of the dust emission for wind velocities of 5, 7, and 10 m/s and within the range of relative humidity from 10 divided by 50% into SCREENVIEW software, the obtained values on the diagram showed good agreement with those of measurements on site. The simulation, that considered the landscape and wind increases over a 20 year period, showed that the dust concentration will be over the Maximum Allowable Concentration (MAC) up to 1400 m from the deposit, for an average wind speed of 3.0 m/s, a relative humidity of 37% and up to 4000 m under unstable weather conditions.

AB  - Phase diagram of the ternary Au-Cu-Sb system was investigated experimentally by DTA and SEM-EDS methods and analytically by CALPHAD method. The liquids projection, invariant equilibrium, several vertical sections and isothermal section at 300 degrees C were predicted using COST 531 thermodynamic database. Phase transition temperatures of alloys along four predicted vertical sections of the Au-Cu-Sb ternary system with molar ratios Au:Cu = 1, Cu:Sb = 1, Au:Sb = 1 and x(Au) = 0.2 were measured by DTA (differential thermal analysis). Predicted isothermal section at 300 degrees C was compared with the results of the SEM (scanning electron microscope) with EDS (energy dispersive spectrometry) analysis from this work This Au-Cu-Sb system belongs to the group of gold alloys, as potential candidates for new lead-free solder materials.
