Abstract A silver/silver chloride reference electrode for use in molten salts is described. Since a commercial porcelain tube conductive to codium and potassium tons is used as the diaphragm, the junction potential between the liquid salts and solid porcelain membrane is definite. The tubular type of construction helps to protect the silver chloride inside the tube from mixing with and contamination by salts outside the tube. The porcelain tubes are industrial products of our country. Experimental results show that the electrode is stable, reproducible and reversible in the temperature range between 700 and 900℃. No significant membrane asymmetric potential is found in comparing two porcelain tubes of different composition. The main advantage of the silver/silver chloride with porcelain diaphragm over the conventional reference electrode with glass diaphragm is that it can be used at higher temperature up to 900℃.
