The interdiffusivity of FeO-CaO in the liquid FeO-CaO-Si0_2 slag contained in an iron crucible has been measured in the temperature range 1573 to 1673 K using the electrochemical method. The experimental technique was the chronopotentiometry at constant currents using the following cell, solid Pel liquid FeO-CaO-Si0_2 l solid Fe The interdiffusivity depends on the basicity parameter B of the slag, and the interdiffusivity is calculated experimentally as follows. D^^〜/m^2s^<-1>=1.03×10^<-2> exp(-8.10B+(38300B-43500)/T The interdiffusivity is inversely proportional to the viscosity. These results show that the interdiffusivity is governed by the silicate structure and the amount of silicate.
