Study of deoxidization process of CsI melt by the action of "Zr-Pt" galvanic couple
The course of removal of oxide ion admixtures (deoxidization) from molten cesium iodide using galvanic couple zirconium-platinum at 973 K was studied by a potentiometric method using a membrane oxygen electrode Pt(O₂)⁄YSZ (YSZ - yttria stabilized zirconia) as an indicator one for the detection of cu...
