摘要: 文中叙述了熔盐中使用的银/氯化银参比电极。因为采用了由钠、钾离子导电的陶瓷管作为隔膜,所以熔盐和隔膜间的接界电位也就是确定的。而且这种管状的结构防止了管内熔盐被管外的熔盐沾污和混合,试验结果表明,在700℃—900℃范围电极是稳定的、重现的与可逆的,也没有发现值得注意的膜的不对称电位。

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℃.
