Dimethyl formamide solvates of CaCl2

Thermochimica Acta, 1981
Abstract 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 ...

Characterization of the CaCl2EuCl2 and CaCl2SrCl2 systems by X-ray powder diffraction

Journal of Solid State Chemistry, 1987
The systems CaCl2SrCl2 and CaCl2EuCl2 were studied over the entire composition range by X-ray powder diffraction. The CaCl2XCl2 (X = Sr, Eu) systems behave similarly and exhibit two single-phase regions with corresponding adjacent two-phase regions. The first single-phase region exhibits the SrI2-type and the second the SrBr2-type structure.

Thermodynamic properties and phase transitions of salt hydrates between 270 and 400 K IV. CaCl2·6H2O, CaCl2·4H2O, CaCl2·2H2O, and FeCl3·6H2O

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.

Partition coefficient of CaCl2 in NaCl

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1971
1. The concentration dependence of the equilibrium partition coefficient of CaCl2 in NaCl was determined. 2. Possible reasons are indicated for the jump-like change in the partition coefficient near the melting point of NaCl.

Phase change stability of CaCl2·6H2O

Solar Energy, 1984
Abstract A CaCl2·6H2O composition with a slight excess of water was found very stable on repeated phase change (over 1000 cycles) in a heat cycle test (35 ∼ 18°C), using vertical glass tubes of 950 mm height. The mole ratio of water CaCl 2 , n, was 6.11, less than that of the peritectic composition (n = 6.14).

Thermal decomposition of Ca2SiO4·CaCl2

Cement and Concrete Research, 1971
Abstract High-temperature microscopy, high-temperature X-ray diffraction, DTA and TGA indicated that synthetic Ca2SiO4·CaCl2 decomposes according to the reaction The direct development of ga′-Ca2SiO4 from structural relics of decomposed Ca2SiO4·CaCl2 is proposed.

Solubility of Calcium in CaCl2-CaO

ECS Transactions, 2008
The 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%.

Salt effect on vapor–liquid equilibria for binary systems of propanol/CaCl2 and butanol/CaCl2

Fluid Phase Equilibria, 2005
Abstract 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.

The MgCl2KClCaCl2 phase diagram

Thermochimica Acta, 1993
Abstract The MgCl 2 KClCaCl 2 phase diagram has been determined using the method of thermal analysis. The liquidus system is a simple one with two eutectics at MgCl 2 (48 mol. %)—KCl (40 mol. %)—CaCl 2 (12 mol.%), m.p. 722 K; and MgCl 2 (35 mol.%)—KCl (63 mol.%)—CaCl 2 (2 mol. %), m.p. 700–725 K.
