OXYGEN ION SENSING ELECTRODE FOR HIGH-TEMPERATURE MOLTEN SALT SYSTEM AND QUANTITATIVE ANALYSIS OF OXYGEN ION USING THE SAME

摘要

PURPOSE: A hot-melt salt oxygen ion sensor electrode and an oxygen ion measurement method are provided to use in a metal ingot manufacturing process or a uranium collecting process of a dry separation process by regularly controlling the chemical condition of molten salt. CONSTITUTION: A hot-melt salt oxygen ion sensor electrode comprises a heat convection cutoff pipe and a carbon electrode. The carbon electrode is located at the center of the heat convection cutoff pipe. The heat convection cutoff pipe is made of one selected from the group consisting of glass, quartz, crystal, and ceramics. The oxygen ion sensor electrode measures the oxygen ion amount within the hot-melt salt. The oxygen ion sensor electrode blocks the convection of the molten using the heat convection cutoff pipe and measures current according to diffusion.
