High-Temperature Electrochemical Research in Metallurgy.

Abstract

Various types of novel high-temperature electrochemical devices incorporating solid, oxygen ion-conducting electrolytes were designed, analyzed, and tested for potential application in research and industrial metallurgical processing. Devices for measurement and/or control of the thermodynamic activity of oxygen (and related non-metallic components) in stagnant or flowing gases and in solid and liquid metals; for the continuous coulometric deoxidation of molten metal streams; for the measurement of thermodynamic and kinetic parameters of metallurgical reactions; and for the determination of sulphur contents in molten alloys and slags were specifically investigated. Scientific data were obtained on the electrical conductivity characteristics of commercial solid oxide electrolyte materials (including local cell effect); on the fundamental principles of operation of solid-electrolyte electrochemical cells as oxygen pumps; and on the diffusivity and solubility of oxygen in molten copper, silver, lead, and iron.
