Miner., 54, 1684–1710 (1969). Assoc., Mon., No. Miner. Stand. In the mining industry, the minerals bornite or chalcopyrite, which consist of mixed copper-iron sulfides, are often referred to as "copper sulfides". The thickness of the inner-disk layer can be tuned to form two-dimensional (2D), single atomic layers (<1 nm).

The sulfide phase compositions (Table 3) represent either a spot analysis or the average ofup to five spot analyses. This bond length difference has been ascribed to the higher bond order in (S-S)− compared to (S-S)2− due to electrons being removed from a π* antibonding orbital. Abt., 28, 35–47 (1957) in German. Geol., 68, 455–465 (1973). Res., 4, 205–212 (1976).

Luxová 257 Monitoring of Hydrocarbon Gaseous Compounds formed During Bioleaching of Copper Sulphide Minerals with Mesophilic Microorganisms. Different stoichiometric compositions can be obtained by changing the redox atmosphere of the synthetic environment. Sulfide minerals are compounds in which sulfur is combined as an anion with a metal (or semi-metal) cation or cations. Copper sulfate, also known as copper sulphate, are the inorganic compounds with the chemical formula CuSO4(H2O)x, where x can range from 0 to 5. Chem. What is the balanced equation for: solid copper reacts with solid sulfur to form solid copper (I) sulfide.? Polymer samples were immersed for 4and 5 h in 0.15 mol⋅ solutions and acidified with HCl(0.1 mol⋅) at . Relevance. Rend., 249, 259–261 (1959) in French. Chem., 5(7), 1296–1297 (1966). Leksina, T.

Depending on their composition, these copper sulfides are either semiconductors or metallic conductors. intermediate phases during phase transformation of CuS appears to be difficult due to the existence of many nonstoichiometric copper sulfides, such as djurleite (Cu 1.96 S), digenite (Cu 1.8 S), and anilite (Cu 1.75 S) in addition to the most stable covellite (CuS) and chalcocite (Cu 2 S) phases, especially Metall., 8, 128–132 (1979).

Kordes, “Anomalies in Equilibrium of Reaction [Cu2S]+(H2)⇆2[Cu]+(H2S)”,Z. Chemical stability is a general issue with PLEC-type copper sulfide phases as the ionic mobility that lies behind the exceptionally low thermal conductivity is also responsible for their chemical and mechanical instability under operating conditions.
