摘要：

Potentials for the thermal cell (25°C) Ag-AgCl/KCl/AgCl-Ag(T°C) as a function of the concentration of KC1 (0.0050-0.505M) and temperature (T = 25°-275°C) are reported. The thermal cell potentials are combined with isothermal potentials for the silver-silver chloride electrode at elevated temperatures to calibrate external Ag/AgCl electrodes as pseudothermodynamic standards for the investigation of electrochemical processes in high temperature aqueous systems. © 1979, The Electrochemical Society, Inc.
