Abstract: An electrode for measuring the pH of a liquid at high temperatures and pressures comprises a first hollow electrode formed of the ceramic which exhibits a pH-dependent potential thereacross and a second electrode provided with a porous ceramic junction. Two flexible-walled members are in fluid communication with the hollow interior of the two electrodes and are surrounded by a chamber whose pressure is kept substantially the same as that to which the electrodes are exposed. However, the chamber is thermally insulated from the hot solution whose pH is being measured. The interiors of the hollow electrodes and the flexible-walled members are filled with the same buffered solution and measuring electrodes are disposed within each of the flexible-walled members. The construction enables the measuring electrodes to be kept at substantially room temperature, thereby reducing chemical attack thereon and eliminates errors in potential measurement due to streaming and thermal diffusion potentials.

Abstract: A reference electrode for use in measuring electrochemical corrosion potential and pH of, for example, water in a drum boiler at supercritical temperatures and which is corrosive includes an alumina or zirconia tube which is packed with a bulk solid electrolyte. The electrolyte consists of a mixture of silver chloride and glass in an optimally 2 to 4 weight ratio or glass particles with silver chloride precipitated around each particle. A solidified silver chloride electrode interfaces with the bulk electrolyte and has embedded in it a conductive silver electrode which provides the electrical contact. Use of the foregoing provides an immobilized solid electrolyte which displays stability and integrity as the temperature and pressure cycles between extremes.

Abstract: A system for measuring the potential between a working electrode in a pressurized, high temperature environment containing a solution which supports electrolytic conduction and a reference electrode is disclosed herein. This system utilizes an external reference electrode assembly which includes a particular technique of balancing its own internal pressure with the pressure in the high temperature environment in order to eliminate streaming potentials between the working electrode and the reference electrode. This assembly also includes a technique for maintaining the concentration of electrolytic solution at a substantially fixed and uniform level so as to maintain a fixed thermal liquid junction.
