โฆ Synopsis
the measurements. The polarization measurements were conducted by applying a constant current (1 mA) between the two RuO 2 electrodes. The voltage was measured as a function of time at 700 8C. RuO 2 electrodes were utilized when the atmosphere contained Cl 2 because this would react with Pt electrodes. DC conductivity determination was based on the voltage, applied current, RuO 2 electrode surface area, and pellet thickness. Details of similar experiments are described elsewhere. [7] The relative density and the Vickers hardness of the pellets were measured by a Micromeritics (AccuPyc 1330) porosimeter and a Shimadzu Micro Hardness Tester (HMV-2).
