The electrical resistivity of stabilized zirconia of various compositions has been measured by a four-probe technique in the temperature range 550 ~ 1200~ Resistivities of fully stabilized compositions are found to increase with increasing additions of the stabilizing oxide, and the lowest resistivities appear to occur in materials stabilized with small cations.
