Copper sulfides can be classified into three groups: Monosulfides, 1.6 ≤ Cu/S ≤ 2: their crystal structures consist of isolated sulfide anions that are closely related to either hcp or fcc lattices, without any direct S-S bonds. NaHS sulfurizes oxidized copper species, but not oxidized iron species. Description. The copper ions are distributed in a complicated manner over interstitial sites with both trigonal as well as distorted tetrahedral coordination and are rather mobile. Cleavage is perfect in one direction forming thin sheets. (2009, January 23). [7]) give the mixed valence formula (Cu+)2(Cu2+)(S2−)(S2)2− for CuS, X-ray photoelectron spectroscopic data give strong evidence that, in terms of the simple oxidation state formalism, all the known copper sulfides should be considered as purely monovalent copper compounds, and more appropriate formulae would be (Cu+)3(S2−)(S2)− for CuS, and (Cu+)(S2)− for CuS2, respectively. Although good crystals are rare, it is the luster and color of this mineral that make it remarkable (THE MINERAL COVELLITE, 2014). Prominent copper sulfide minerals include Cu2S (chalcocite) and CuS (covellite). Alginate-based functional nanocomposite films were prepared by the incorporation of copper sulfide nanoparticles (CuSNP) using a solution casting method and characterized their properties. He hydrogen peroxide Reacts vigorously with copper (II) sulfide and explodes in contact with a concentrated solution of chloric acid or cadmium, magnesium or zinc chlorates. However, it is not the main mineral of copper due to its scarcity. Figure 4: appearance of copper (II) sulfide. • Oxidized iron species dissolve as the complex ion then reprecipitates as ferric oxide. Immediately induce vomiting. Copper sulfides describe a family of chemical compounds and minerals with the formula CuxSy. Therefore, this group of copper sulfides shows ionic conductivity at slightly elevated temperatures. The majority of sulfides are metallic, opaque, generally sectile, soft to average in hardness and they have high densities, black or dark-colored streaks, and an igneous origin. Retrieved from pubchem.ncbi.nlm.nih.gov. [11][12]. There are several copper ores, but they all fall into two main categories: oxide ores and sulfide ores. Both minerals and synthetic materials comprise these compounds. The optical properties of these Cu2−xS NCs were characterized by UV−vis spectroscopy and NIR. Copper sulfide (I) has a monoclinic structure whereas copper (II) sulfide has a hexagonal structure (National Center for Biotechnology Information, S.F.). Strong generalities exist in this class. In virtually all of the sulfides, bonding is covalent, but some have metallic properties. Some copper sulfides are economically important ores. Copper (I) and (II) sulphides are not classified as hazardous, however they may be toxic if swallowed due to the production of hydrogen sulphide. It can be classified into three groups, namely monosulfide, disulfide and mixed monosulfide. Whatever their source, copper sulfides vary widely in composition with 0.5 ≤ Cu/S ≤ 2, including numerous non-stoichiometric compounds. Dicopper (1+) sulfide.

All presented Cu2−xS NCs show a blue shift in the band gap absorption compared to bulk Cu2−xS. THE MINERAL CHALCOCITE. Its crystal structure is analogous to that of pyrite, with all sulfur atoms occurring as S-S units. (2015). Actually 1 kg copper sulphate requires only 0.225 kg of chemically pure hydrated lime to precipitate all the copper. On the other hand, copper (II) sulfide finds applications in solar cells, superionic conductors, photodetectors, electroconductive electrodes, photothermal conversion devices, microwave protective coating, active radio wave absorbers, gas sensors and radiation polarizers Infrared (azom, 2013). Copper sulfides can be classified into three groups: Monosulfides, 1.6 ≤ Cu/S ≤ 2: their crystal structures consist of isolated sulfide anions that are closely related to either hcp or fcc lattices, without any direct S-S bonds. Symptoms include vomiting, gastric pain and dizziness, may cause irritation to the skin and eyes and inhalation may cause respiratory irritation (MATERIAL SAFETY DATA SHEET Copper Sulfide, 1995). Further evidence that the assignment of the so-called "valence hole" should be to the S2 units in these two formulae is the length of the S-S bonds, which are significantly shorter in CuS (0.207 nm) and CuS2 (0.203 nm) than in the "classical" disulfide Fe2+(S2)2− (0.218 nm). W. G. Mumme, R. W. Gable, V. Petříček, Canadian Mineralogist; (2012); 50; 423-430. While the liquid-like Cu ions play an important role for the low κ L and high ZT values, grain-boundary engineering is needed to further enhance the phonon scattering and the thermal stability of Cu 2- x S. Different stoichiometric compositions can be obtained by changing the redox atmosphere of the synthetic environment. Classes of copper sulfides. It is not flammable or combustible.
