We studied some properties of molten slags for steel making electrochemically. (1) Several specific electric conductivities in molten state were measured by D. C., or A. C. source. Slags containing FeO are good conductors nearly equal to salt aqueous solutions. Its order is 10^<-1> Ω^<-1> cm^<-1> in 1400∿1500℃. (2) By electric decomposition making use of D. C., A. C. or D. C. & A. C., different sorts of molecules distinguished by microscopic examination are gathered about anode and cathode of Pt plates. (3) Apparent decomposition potential or polarisation one were determined by voltage-current curves or electromagnetic oscillograph apparatus. (4) Molten slags dissociate in one part and single ions and complex ones are movable in action of electric field. After calcurating △F for dissociation, ion valency or moving ion pairs taking part in the reaction were estimated as integer.
