The Anodic Dissolution and Passivation of Zinc in Concentrated Potassium Hydroxide Solutions
R. W. Powers,M. W. Breiter +1 more
TL;DR: In this article, two sets of experiments were carried out to obtain a better understanding of the tendency of the alkaline zinc electrode to passivate either photomicrographs of the electrode surface were taken in situ at different potentials during an anodic voltage sweep or the two components of electrode impedance were measured with a small signal of superimposed 1000 Hz AC.

The Electrophoretic Forming of Beta‐Alumina Ceramic
TL;DR: In this paper, electrophoretic deposition is shown to be an operationally simple, rapid, and reliable technique for forming a wide range of beta-alumina shapes required in electrochemical devices.

An Analysis of the Impedance of Polycrystalline Beta‐Alumina
R. W. Powers,S. P. Mitoff +1 more
TL;DR: In this paper, a procedure is described for distinguishing in the measured electrical properties of polycrystalline β-alumina, the separate contributions of the grain boundaries and of the crystal, i.e., the grain interiors.

Film Formation and Hydrogen Evolution on the Alkaline Zinc Electrode
TL;DR: The duplex structure of anodic films formed in concentrated solutions with convection nearly absent has been confirmed on high-purity polycrystalline zinc and to a more limited extent on some polycrystaline zinc alloys as well as discussed by the authors, and experimental conditions required for following stages in the formation of the precipitated film, the one most difficult to observe, are defined more explicitly in this paper.
