Application of Square-Wave Stripping Voltammetry for the Analysis of Lead–Bismuth Electrodeposits

Abstract

The possibility of targeted electrodeposition of metal coatings in the lead–bismuth binary system is considered. The analysis of metal content in the deposits is performed using square-wave stripping voltammetry of solutions containing both lead and bismuth. The results are supported by the data of scanning electron microscopy, energy-dispersive X-ray spectroscopy, and X-ray diffraction analysis. The conditions for the formation of Pb₇Bi₃ (ε-phase), which is promising for the application in superconducting microelectronics, are found.
