Thermodynamic calculations on phase equilibria involving fused salts; part I, General theory and application to equilibria involving calcium carbonate at high pressure



Thermodynamic calculations on phase equilibria involving fused salts; part I, General theory and application to equilibria involving calcium carbonate at high pressure



American Journal of Science 260(5): 374-382



A theory is developed for determining melting-point curves of salt mixtures and of salt mixtures containing small amounts of other ions. Depression of the curves is illustrated for NaCl + NaF and CaO + CaCl (sub 2) at atmospheric pressure and then applied at 1000 bars to the system Ca(OH) (sub 2) -CaCO (sub 3) . The presence of 1.35 weight percent of water is calculated to lower the eutectic temperature in this system by 10 degrees C.
