A newly designed Ag/Ag reference electrode in a quartz tube with a tungsten tip junction (W-tip-Quartz-REF) was fabricated and its electrochemical performance was compared with a conventional Pyrex tube-based Ag/Ag reference electrode (Py-REF). The results of the electrochemical potential measurements with the W-tip-Quartz-REF and the Py-REF in the LiCl-KCl eutectic melts for a wide temperature range proved that the oxide layer on the Surface of the tungsten metal tip provided a high ionic conduction. Stability Of Our newly designed W-tip-Quartz-REF was tested by measuring a junction potential for 12 hours at 700 degrees C. The results of the cyclic voltammetric measurement indicated that the Ag/Ag reference electrode in the quartz tube with a tungsten tip junction can provide a good performance for a wide temperature range.
