Potentiometric measurements in fused salts: The principle and the construction of an oxygen electrode having a Th0.8 Y0.2 O1.9 solid electrolyte membrane which conducts oxide ions

摘要

Deportes et al. [l,2] described an oxygen electrode with a protective layer of ZrO2 solid electrolyte which selectively allowed the passage of oxide ions. A CaO-stabilised ZrO2 having purely oxygen-ion conduction was used and this material acted as a membrane between an air-flushed platinum electrode and the molten bath of salts containing oxy-anions.
