Abstract

A simply constructed, stable, Ni/Ni²⁺ saturated reference electrode (SRE) has potential to measure thermodynamic behavior of molten chloride salts more reliably. Like the Ag/Ag⁺ reference electrode (RE), the Ni/Ni²⁺ SRE is made of commercially available materials. Initial experiments in molten CaCl2 and LiCl show the Ag/Ag⁺ RE potential drifting two times faster than the SRE. Furthermore, experiments show the replicability of SREs by comparing two Ni/Ni²⁺ SREs with different compositions of NiCl₂ which is supportive of saturated phase behavior.
