Key parameters determining structure and properties of sulphide films formed on copper corroding in anoxic sulphide solutions
The corrosion behaviour of copper was studied in anoxic solutions containing different concentrations of sulphide (10–10 mol L) and chloride (0?1–5 mol L) under stagnant and controlled convective conditions. The main determinants of the structure and properties of the copper sulphide (Cu2S) films formed are the rate of sulphide transport to the surface relative to the rate of its interfacial re...
متن کاملA Laboratory Study of Removing Arsenic from a Synthetic Copper Concentrate
Arsenic is the 20th most abundant element in the earth's crust at a level of about 2 ppm. It is a constituent of over 300 minerals and is commonly found in non-ferrous ores such as copper, lead, zinc, gold and uranium. Efficient separation of arsenic minerals from other sulphide minerals is of great importance for the metallurgical performance of flotation processes. This work was undertaken to...
متن کاملEffect of Thickness on Properties of Copper Thin Films Growth on Glass by DC Planar Magnetron Sputtering
Copper thin films with nano-scale structure have numerous applications in modern technology. In this work, Cu thin films with different thicknesses from 50–220 nm have been deposited on glass substrate by DC magnetron sputtering technique at room temperature in pure Ar gas. The sputtering time was considered in 4, 8, 12 and 16 min, respectively. The thickness effect on the structural, mo...
متن کاملFormation of Cupric Oxide Films on Quartz Substrates by Annealing the Copper Films
In the present work, cupric oxide (CuO) films were obtained through thermal annealing of the copper (Cu) films deposited on quartz substrates by DC magnetron sputtering method. The annealing was performed in air atmosphere for different times ranging from 60-240 min at temperature of 400 ºC. The influence of annealing times on structural and morphological properties of the films was investi...
متن کاملUltrasonic Spray Pyrolysis Deposited Copper Sulphide Thin Films for Solar Cell Applications
Polycrystalline copper sulphide (Cu x S) thin films were grown by ultrasonic spray pyrolysis method using aqueous solutions of copper chloride and thiourea without any complexing agent at various substrate temperatures of 240, 280, and 320°C. The films were characterized for their structural, optical, and electrical properties by X-ray diffraction (XRD), scanning electron microscopy (SEM), ener...
