“…In the polarization cells (--) Bi]BiF~IPt, or Ag (-t-) similar current instabilities occurred as observed by Van der Meulen and KrSger (12) in their study of the electronic conductivity of silver halide& Above 350°K these instabilities were not observed for Ag anodes. Although these current instabilities interfered with determining steady-state currents, voltage-independent steady-state currents of the order of 5 X 10-t°A were measured up to 1.5V at 313°K for the cell (--)BilBiF31Pt(+).…”

Concentrated fluoride-excess solid solutions based on the alkaline earth fluorides and with CeF~ and UF4 as dopants are suitable solid electrolytes for application in thin film galvanic cells. Galvanic cells were fabricated using Pb or Ca as the anode, the concentrated solid solutions as electrolytes, and either BiF3 or BiO0.1F2.s as the cathode. Discharge characteristics were studied in air from 300 ° to 540°K. The cells are rechargeable. The electrical properties of BiF3 were studied and compared with data reported for BiOo.lF2.s.

“…5, the single black curve represents the electronic conductivity calculated for a divalent impurity concentration of 0.1%, showing a significant decrease relative to the pure material. Measurements of the electronic conductivity at low temperatures by van der Meulen and Kroeger 33 indicate that an unintentional impurity doping will always lead to a somewhat lower electronic conductivity than that calculated in Fig. 5.…”

Experiments on the generation of non-equilibrium surface patterns on ion-conducting thin films (AgCl, silver chloride) during field-driven growth in chlorine rf plasmas are reported. The growth experiments are performed in a vacuum flow reactor in the temperature range between 320 K and 450 K, at chlorine gas pressures in the order of 100 Pa, and by applying current densities in the order of 1 mA cm(-2). The surface morphology of product films is documented by scanning electron microscopy and analysed in terms of typical surface patterns. A large variety of different surface morphologies (often finger-like or dendritic) is prepared with a high lateral uniformity and good reproducibility. A theoretical stability criterion is derived on the basis of a linear stability analysis. The model-type experiments confirm this formal stability criterion: (a) The growth of the product surface is morphologically stable, if the plasma exhibits a higher conductivity than the growing solid. (b) The typical wavelength of the surface patterns that are formed during growth is proportional to the reciprocal root of the electric current. (c) The periodicity of the surface patterns decreases when the temperature is increased, and the growth rate of a surface instability grows with increasing temperature. All theoretical predictions are confirmed by corresponding experimental results.

Measurements of the direct current-voltage characteristics of calcia-stabilized zirconia using platinum electrodes of various types have been made to investigate possible electrode processes. Depending on the form of the electrode, the rate-limiting step in the electrical conduction sequence can be (a) ionic conduction by O = in the zirconia, (b) electronic conduction in the zirconia, (c) oxygen atom diffusion through the platinum cathode, (d) the transfer of oxygen from the gas phase into the zirconia at the zirconia-gas interface on the cathode side. The conditions, under which each of these situations exists, are explained in terms of the structure of the electrode.Earlier studies on cells Pt, 02[0.85 ZrO2 9 0.15 CaOIPt, 02 with platinum point electrodes (1), or porous platinum electrodes (2), showed the I-V characteristic to be markedly nonohmic. The rate-controlling step responsible for this behavior was found to be confined to the cathode. Two mechanisms of electrode operation appeared to be important (2).
