Thermodynamic properties and phase equilibria of the secondary copper minerals libethenite, olivenite, pseudomalachite, kröhnkite, cyanochroite, and devilline
Original language description
The thermodynamic properties of libethenite [Cu2(PO4)(OH)], olivenite [Cu2(AsO4)(OH)], pseudomalachite [Cu5(PO4)2(OH)4], cyanochroite [K2Cu(SO4)2 6H2O], kröhnkite [Na2Cu(SO4)2 2H2O], and devilline [CaCu4(SO4)2(OH)6 3H2O] were determined by a combination of acid-solution calorimetry (enthalpy of formation) and relaxation calorimetry (heat capacity and entropy). The calculated Gibbs free energies (in kJ mol–1) for these phases are –1229.3 4.5, –848.7 4.8, –2837.9 10.8, –3441.4 3.9, –2442.3 3.6, –3843.2 8.4, respectively. The phases studied were characterized by powder X-ray diffraction, infrared and Raman spectroscopy, and electron microprobe, as needed.n
