The ionic conductivity of lanthanum oxychloride has been measured by using the method of plotting graphs of impedance in the plane complex. The ionic conductivity measurements were made for the temperature limits (300 - l400)oC. The determined·activation energy at low temperature agrees with that measured for PbCl2 and SrCl2 as given respectively,1,2,3, while the value at high temperature shows a slight agree,ent with measurements made on Th02- Y01.5 15% , La203 -caO and La203 - srO of Hammou .and VanbaeliDghem.
