| Abstract: | Solubilities of TiO2, Cr2O3, and NiO in molten eutectic mixtures of LiF-ZrF4, NaF-ZrF4, and KF-ZrF4 systems were studied in a temperature range of 873–1073 K using isothermal saturation, inductively coupled plasma-mass spectrometry (ICP-MS), and X-ray powder diffraction. The solubility mechanism was found to depend on the acid strengths of cations in the oxide and solvent melt. In all of the systems studied, the temperature-dependent solubility is fitted by a linear equation: lnS = a ? b/T. The dissolved oxide is shown to influence the electrical conductivity of molten salt mixtures. |
