Measurements of the electrolyte overall resistance as well as the grain volume and boundary resistances comprising it, reveal that the grain volume resistance remains constant while that of grain boundaries and accordingly of the electrolyte decreases with the increase of the average grain size and sintering temperature. The activation energy for conductivity of the grain boundaries is higher than that of the grain volume due to which at high temperatures the electrolyte conductivity is mainly determined by the grain conductivity, while at low temperatures it is the boundary conductivity that matters.
1997 vanadium, V vanadium, V I 5000 04 -028 Ammonium -Cerium(III) Polyvanadates. -Two novel polyvanadates, (NH4)1.78(CeOH)0.11V6O16·0.5 H2O and ( NH4)0.64(CeOH)0.18V5O13·5 H2O, are synthesized by hydrolytic precipitation from vanadium-containing nitric solutions at 90 • C. IR-spectra, thermal and electric properties are studied. -(KRUCHININA, M. V.; VOLKOV, V. L.; KORYAKOVA, O. V.; PALKIN, A. P.; INOZEMTSEV, M. V.; Zh.
ChemInform is a weekly Abstracting Service, delivering concise information at a glance that was extracted from about 100 leading journals.
