Abstract
The single-crystal material has a resistivity at 300 degrees C of 4.7 Omega cm and an activation energy of 0.13 eV. In the polycrystalline case it has been possible to separate out the bulk and grain boundary contributions to the total electrolyte resistance. These have activation energies of 0.15 and 0.26 eV respectively. The grain boundary or intergranular contribution becomes negligible above 200 degrees C and the sample resistivity at 300 degrees C is 15.4 Omega cm. The resistivity results obtained were independent of the electrode material used although this did affect the measured interfacial capacitance.Keywords
