Solubility of magnesium oxide in calcium oxide-calcium chloride mixtures

Fundamental theories and concepts for predicting thermodynamic properties of high temperature ionic and metallic liquid solutions and vapor molecules

“…This term is positive if ⌬GЊ led to an important conclusion that the excess free energy of is the standard free-energy change for Eq. [11] with all mixing of an ionic mixture could be represented by a simple constituents being liquid. The sign of this term is also posipolynomial similar to that deduced for atoms with only nearesttive if AY is not chosen as a component and will be negative neighbor interactions.…”

“…Even though the equations used are only second-order, the accuracy of calculations is improved only from a second-order perturbation theory for reciprocal salt if higher-order expressions for the binary excess free enersystems, calculations from these equations exhibit surprising gies of mixing are used, such as accuracy for systems in which the quantity of ⌬GЊ for Eq. [11],…”

“…coulomb interactions, and it was used to prove that equations [11]) tend to associate and form larger-than-random numbers deduced intuitively from standard-solution concepts based on of nearest-neighbor pairs. This term, although it is not very short-range interactions were valid for ionic systems with longlarge in a large number of cases, is significant for the calcularange interactions.…”

“…. [5] AX ϩ BY ⇔ AY ϩ BX [11] Activity coefficients represent the deviations of solution If the standard free-energy change for Reaction [11] is posiproperties from those of a hypothetical ideal solution. Thus, tive, then the two stable constituents, AX and BY, both tend in order to define activity coefficients, we have to first define to exhibit positive deviations from ideal behavior, whereas an ideal solution.…”

“…Calculations of of AY with added BX to that with no added BX, which is solubilities and solubility products have been made using an activity coefficient (␥ * AY ) defined as unity at infinite diluthis cycle [4] for fundamental studies [10] and for systems of tion of BX: technological significance. [11,12] In these references, the solvents were sometimes more complex than a simple salt such…”
