Stability of the gold mercaptotriazole complex at pH=4
(Bor : Mining and Metallurgy Institute, 2018)
The objective of this work was to investigate the stability of the gold complex based on
mercaptotriazole in slightly acid media, at pH=4. The gold complex complex was studied by the visual monitoring and electrochemical ...
SEM-EDS analysis of gold mercaptotriazole crystals (Au-MT)
(Belgrade : Serbian Society for MicroscopyBelgrade : Institute for Biological Research "Siniša Stanković", 2019)
An electrolyte based on gold complex with mercaptotriazole was synthesized in a wide pH range
from acid to alkaline (pH=2-12). After synthesis of the electrolyte, detailed characterization of the
complex in liquid and ...
CHARACTERIZATION OF THE ANODIC FILMS FORMED ON THE Ag60Cu26Zn14 ALLOY BY THE LDI MASS SPECTROMETRY
(Bor : Mining and Metallurgy Institute, 2018)
Precise, direct and fast methods for characterization the anodic films still have to be developed, since the conventional methods cannot be accelerated beyond the certain limits. The present work uses a laser desorption/ionization ...
MASS SPECTROMETRY FOR STRUCTURAL CHARACTERIZATION OF NON-CYANIDE GOLD COMPLEX
(Bor : Mining and Metallurgy Institute, 2015)
In this work, the possibilities of a mass spectrometry approach towards the characterizations of the electrolyte for decorative gold plating based on mercaptotriazole were studied. All mass spectra were obtained using laser ...
RAMAN SPECROSCOPY STUDY OF ANODIC FILM ON Ag43Cu37Zn20 ALLOY
(Bor : Mining and Metallurgy Institute, 2015)
The aim of the present work is characterization of electrochemically treated Ag43-Cu37-Zn20 alloy in near neutral chloride solutions by the X-ray diffraction and Raman spectroscopy. At potential of +0.25 V, a complex ...
Stability of gold complex based on mercaptotriazole with gold concentration lower than optimal
(Bor : University of Belgrade, Technical Faculty, 2017)
The aim of this work was to investigate the stability of the gold complex based on mercaptotriazole at optimum pH value of nine in the electrolyte with gold concentration of 1.5 g/dm3. Investigations were performed by ...
Influence of silicon on characteristics of sterling silver
(Bor : University of Belgrade, Technical Faculty, 2017)
The scope of the presented study refers to the mechanical and electrical properties of the sterling silver in relation on silicon content in the alloy. Sterling silver is an alloy of silver containing 92.5% by weight of ...
THE INFLUENCE OF RHODIUM CONTENT ON THE MECHANICAL PROPERTIES OF PLATINUM
(Bor : Mining and Metallurgy Institute, 2015)
The paper presents the results of investigation the influence of rhodium as an alloying element on the mechanical properties of platinum. A short-term and tensile strength were tested, at room and high temperatures, and ...
