Thermodynamic Assessment of PrCl3-CaCl2 and NdCl3-CaCl2 Systems
Journal of Phase Equilibria and Diffusion, 2010By using the CALPHAD technique, an assessment of the binary PrCl3-CaCl2 and NdCl3-CaCl2 systems have been carried out. From measured phase equilibrium data and experimental integral properties, the PrCl3-CaCl2 and NdCl3-CaCl2 phase diagrams were optimized and calculated.

Cathodic behavior of molten CaCl2-CaO and CaCl2-NaCl-CaO
International Journal of Minerals, Metallurgy, and Materials, 2010The cathodic behavior of molten CaCl2, CaCl2-CaO and equimolar CaCl2-NaCl-CaO was studied by cyclic voltammograms and constant potential polarization at temperatures of 1123 to 1173 K on molybdenum and titanium electrodes. The diffusion coefficient of Ca2+ (CaO) in molten CaCl2-CaO was calculated from the linear relationship between the square root of ...

The dislocation structure in NaCl-CaCl2 and NaCl-NaBr-CaCl2 systems
Journal of Crystal Growth, 1978Abstract Dislocation structure in NaCl-CaCl2 grown from melt has been studied using the etch-pit method. Helical dislocations and dislocation loops were found in these crystals. At higher concentrations of calcium the sub-grain-boundary network seems to have been affected.

Enthalpies of mixing in PrCl3CaCl2 and NdCl3CaCl2 liquid systems
Thermochimica Acta, 1994Abstract The molar enthalpies of mixing Δ mix H m in the PrCl 3 CaCl 2 and NdCl 3 CaCl 2 liquid binary systems were measured at 1073 K over the whole composition range under argon at atmospheric pressure. The apparatus used was a Calvet-type high-temperature micro-calorimeter and mixing of the two liquid components was obtained by the break ...

Abstract The CsCl-CaCl 2 phase diagram was investigated following differences in published reports. The diagram contains two eutectics at 8 mol.% CaCl 2 (881 K) and 85 mol.% CaCl 2 (983 K), two peritectics appearing at approximately 15 and 17 mol.% CaCl 2 (931 K and 954 K) and a congruently melting compound, CaCsCl 3 (1182 K).

Phase diagrams for the binary systems CaCl2-KCl and CaCl2-CaCrO4
Thermochimica Acta, 1975Abstract Phase diagrams have been determined using differential thermal analysis for the binary systems CaCl 2 -KCl and CaCl 2 -CaCrO 4 . CaCl 2 -KCl phase diagrams have been previously reported but results were not consistent. No prior studies have been reported for the CaCl 2 -CaCrO 4 system.

Enthalpy of formation of CaCl2·2CH3OH and CaCl2·2C2H5OH by solution calorimetry
The Journal of Chemical Thermodynamics, 1982Abstract Recent thermochemical research on materials suitable for storage of energy has focused on salt hydrates and ammoniates and only limited results exist for the alcoholates of interest in this work. The enthalpies of formation of CaCl 2 ·2CH 3 OH and CaCl 2 ·2C 2 H 5 OH have been determined by solution calorimetry.

The liquidus surface of the CaF2-CaCl2-CaSO4 system has been investigated by differential thermal analysis. Two invariant equilibria (one eutectic and one peritectic) are realized in the system. The eutectic and peritectic melt at 597 and 703°C, and the enthalpies of phase transitions are 206 and 378.1 kJ/kg, respectively.

Tissue calcium levels in CaCl2-induced myelopathy
Neuroscience Letters, 1984CaCl2-induced myelopathy was produced in rats by the application of a solution of CaCl2 to exposed leptomeninges of lumbosacral spinal cord. Equal lengths of remote cervical and lumbar cord were removed at intervals following Ca2+ application. The total Ca2+ in tissue from lumbar cord was significantly elevated over autologous cervical cord and ...
