Abstract By an a.c. impedance technique, the effects of TiC particle on the conductivities of titania slag with composition of 24.3%CaO-23.3%SiO2-13.8%Al2O3-15.3%MgO-23.3%TiO2 were studied in the temperature range of 1723 K to 1633 K. TiC particles in the slag are charge carriers and decrease the conductivities of the slag. The slag containing 0.5%TiC has the lowest conductivity. Increasing the particle size, the conductivities increase. The rate constants and the activation energy of the crystallization reaction of CaTiO3 were calculated based on the first-order kinetic equation.

Key words: titania slag conductivity TiC
