Evaluation of Electrodeposited Lead Dioxide

Abstract

The morphology and phase composition of lead dioxide anodically deposited from various electrolytes was determined as a function of operating parameters. A brittle and rough faceted lead dioxide coating was obtained from lead nitrate electrolytes. The deposit was non-porous and adhered well to a graphite substrate but not to a titanium substrate. A low acid lead nitrate electrolyte with sodium lauryl sulfate additive gave a desirable nonporous, fine faceted lead dioxide coating and improved the adherence of the lead dioxide coating on a titanium substrate. Lead dioxide plated from lead nitrate electrolytes consisted mainly of β- PbO2 and to a lesser extent the α-PbO2 modification. PbO2 plated from a lead fluoborate electrolyte with animal glue as the additive resulted in a non-porus deposit. The deposit was found to adhere well to a graphite substrate and consisted mainly of β-PbO2. Lead dioxide plated from lead fluosilicate and was rather amorphous in appearance. The various lead dioxides showed some differences in polarization behaviour in lead fluosilicate.
