Effects of TiC on the Conductivities of Titania Slag
TiC对高钛渣电导率的影响

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%Al_2O_3 15.3%MgO-23.3%TiO_2 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 CaTiO_3 were calculated based on the first-order kinetic equation
