Description

Electrical conductivities of CaF2-based fluxes for electroslag remelting were measured and the effects of the additions on the conductivity of CaF2 melt were studied. From the results, conduction mechanism of CaF2-based melts were discussed in the term of molar conductivity. The additions of alkali earth metal fluorides and oxides, such as MgF2, BaF2, MgO, CaO and BaO, varied the molar conductivities of CaF2-based melts in accordance with the intensity of cation-anion attraction. It seems that those additions have a tendency to make an ionic pair in the melts. The additions such as Al2O3, TiO2 and ZrO2, may react with fluorine ions to make oxy-fluoride complex ions and then remarkable decreace of electrical conductivity by those additions can be explained.
