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.

Dimethyl formamide solvates of CaCl2
Thermochimica Acta, 1981Abstract The water of hydration in inorganic salts plays a vital role in stabilising their crystal structures, as is evidenced by the fact that on dehydration the structures change radically. In order to understand further the role played by the solvent in the development of an ordered lattice, dimethyl formamide (DMF) solvates of inorganic salts ...

Solubility of Calcium in CaCl2-CaO
ECS Transactions, 2008The solubility of calcium in calcium chloride - calcium oxide is of interest in processes reducing metal oxides in calcium chloride based salt systems. The solubility of calcium in calcium chloride was measured as 2.7mol% at 1073K. This reduced to 0.4mol% at a calcium oxide content of 9.0mol%.

Role of CaCl2 in the reduction of PuO2
Journal of Nuclear Materials, 1985Abstract The phase diagram of CaO-CaCl 2 has been determined. Eutectics at CaO (5 mol%) — CaCl 2 (mp 1020K) and CaO (21 mol%) — CaCl 2 (mp 1102K) were found. The congruently melting compound, CaO.4CaCl 2 , was supported by X-ray diffraction evidence.

The Journal of Chemical Thermodynamics, 1986
Abstract Heat capacities and phase-transition enthalpies between 270 and 400 K have been measured for commercial samples of calcium chloride hexahydrate, tetrahydrate, and dihydrate, and ferric chloride hexahydrate, by adiabatic-shield calorimetry.

Salt effect on vapor–liquid equilibria for binary systems of propanol/CaCl2 and butanol/CaCl2
Fluid Phase Equilibria, 2005Abstract The binary vapor–liquid equilibrium (VLE) data for salt-containing systems of 1-propanol/CaCl2, 2-propanol/CaCl2, 1-butanol/CaCl2 and 2-butanol/CaCl2 were determined and correlated. The UNIQUAC model was used to correlate the VLE data, and optimal parameters of the model were obtained.

1H NMR in CaCl2·xH2O nanocrystals and water sorption isobars in a CaCl2-silica gel system
Journal of Structural Chemistry, 1998Mobility of water molecules in nanocrystals and other phases of CaCl2·xH2O (x=0–12) formed in the nanopores of silica gel during sorption of water vapor is studied by1H NMR. The sorption properties of calcium chloride impregnated in the pores of micro- and mesoporous silica gels were measured.

Solubilities of salts in the ternary systems NaCl + CaCl2 + H2O and KCl + CaCl2 + H2O at 75°C
Russian Journal of Physical Chemistry A, 2011The solubility in the NaCl-CaCl2-H2O and KCl-CaCl2-H2O systems were determined at 75°C and the phase diagrams and the diagram of physicochemical property vs composition were plotted. One invariant point, two univariant curves, and two crystallization zones, corresponding to potassium chloride, dihydrate (CaCl2 · 2H2O) showed up in the phase diagrams of

Solubility of components in the systems MgCl2–CaCl2–H2O and (48.2% CaCl2 + 51.8% MgCl2)–NaClO3–H2O
Russian Journal of Inorganic Chemistry, 2015The solubility in the systems calcium chloride–magnesium chloride–water and (48.2% calcium chloride + 51.8% magnesium chloride)–sodium chlorate–water was studied by the visual–polythermal method. Their polythermal solubility diagrams were constructed. It was determined that most of the solubility diagram of the CaCl2–MgCl2–H2O system is occupied by the

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 ...
