Predicting the copper adsorption capacity on different zeolites / Predviđanje adsorpcionog kapaciteta bakra na različitim zeolitima
(University of Belgrade, Technical Faculty, Bor, 2017)
In this paper the ability of three natural zeolites from different localities (Vranjska banja-VB, Igroš-I and Baia Mare-BM deposits) to remove copper has been investigated. These three zeolites were subjected to the ...
Influence of milling parameters on the preparation of fine tungsten and copper powders by mechanically induced self-propagating reaction / Uticaj parametara mlevenja na dobijanje finih prahova volframa i bakra mehanički iniciranom samorasprostirućom reakcijom
(Savez inženjera metalurgije Srbije, Beograd, 2004)
Mechanically induced self-propagating reaction in planetary ball mill was realized in three different systems, CaWO4 (scheelite) + Mg, CuO + Ti and CuO + Zr. An influence of a ball diameter (from 5 to 41.2 mm) at three ...
Analysis of the properties of a Cu-Al2-O3 sintered system based on ultra fine and nanocomposite powders
(International Institute for the Science of Sintering, Beograd, 2007)
In this paper synthesis of a composite based on Cu-Al2O3 by a thermo-chemical method is shown along with a comparative analysis of the properties of the obtained nanocomposite sintered samples, which are characterized by ...
Comparative analysis of the polarization and morphological characteristics of electrochemically produced powder forms of the intermediate metals
(Macedonian Journal of Chemistry and Chemical Engineering, 2014)
The polarization and morphological characteristics of powder forms of the group of the intermediate metals were examined by the analysis of silver and copper electrodeposition processes at high overpotentials. The pine-like ...
Synthesis and sintering of Cu-Al2O3 nanocomposite powders produced by a thermochemical route
(Savez inženjera metalurgije Srbije, Beograd, 2007)
By hydrometallurgy and powder metallurgy along with prognosis of physical-chemical properties, a synthesis of new improved materials can be successfully performed with in advance pre-set properties which is conditioned by ...
Sintering of Cu-Al2O3 nano-composite powders produced by a thermochemical route / Sinterovanje nano-kompozitnih prahova Cu-Al2O3 dobijenih termohemijskih postupkom
(Serbian Chemical Society, Belgrade, 2007)
This paper presents the synthesis of nano-composite Cu-Al2O3 powder by a thermochemical method and sintering, with a comparative analysis of the mechanical and electrical properties of the obtained solid samples. ...
Overpotential controls the morphology of electrolytically produced copper dendritic forms / Пренапетост контролише морфологију електролитички произведених дендритичних форми бакра
(Belgrade : Serbian Chemical Society, 2019)
The morphologies of copper dendritic forms obtained in both potentiostatic and galvanostatic regimes of electrolysis with various amounts of the electricity were analyzed by the scanning electron microscopy (SEM) technique. ...
Mechanical Properties of Electrolytically Produced Copper Coatings Reinforced with Pigment Particles
(MDPI, 2023)
Copper from sulfate baths without and with added inorganic pigment particles based on strontium aluminate doped with europium and dysprosium (SrAl2O4: Eu2+, Dy3+) was electrodeposited on a brass cathode by a galvanostatic ...
Influence of Electrolyte Impurities from E-Waste Electrorefining on Copper Extraction Recovery
(Metals, 2021)
In order to reflect possible issues in future sole e-waste processing, an electrolyte of complex chemical composition reflecting system of sole e-waste processing was obtained by following a specially designed pyro-elect ...
Electrochemical synthesis and corrosion behavior of thin polyaniline film on mild steel, copper and aluminum
(Belgrade : Association of the Chemical Engineers of Serbia, 2011)
The electrochemical synthesis of polyaniline (PANI) on mild steel, aluminum and copper from the sodium benzoate solutions has been investigated. It has been shown that thin, highly adherent, polyaniline films on the ...
