    摘要: The present invention relates to an electrochemical sensor for determining the concentration of a group IA metal in a fluid such as molten metal. The sensor comprises a substantially pure quantity of the group 1A metal as a reference electrode (13) contained in a sensor housing (3), and a solid electrolyte constituting at least part of the sensor housing (3). The electrolyte is in electrical contact with the reference electrode (13) and the sensor is capable of operating at temperatures in excess of 973K. In a preferred arrangement, the sensor comprises a two part elongate conductor (15), a first part (17) of which extends from the reference electrode (13) into a refractory seal (11a), and a second part (19) of which extends from within the refractory seal (11a) externally of the sensor, the two parts (17, 19) being welded together.

    摘要: The method of electrochemical determination of oxygen partial pressure in ionic melts includes providing a metal/metal oxide reference electrode consisting of an electrode body made of a metal selected from the group consisting of Mo, W, Hf, Nb and Ta and alloys thereof and a layer of an oxide of that metal on the electrode body; immersing a pure platinum electrode and the metal/metal oxide reference electrode in a glass melt; measuring a potential across the metal/metal oxide reference electrode and the pure platinum electrode immersed in the glass melt to obtain a measured potential characteristic of the oxygen partial pressure in the glass melt; obtaining a calibration curve relating the potential across said reference electrode and the pure platinum electrode to the oxygen partial pressure in the glass melt as a function of temperature; and obtaining the oxygen partial pressure in the glass melt from the measured potential and the calibration curve. Either the calibration curve is obtained experimentally by immersing a Zirconium dioxide electrode in the glass melt and measuring a potential difference between the metal/metal oxide reference electrode and the Zirconium dioxide electrode at a plurality of temperatures or theoretically from thermodynamic data for the metal/metal oxide reference electrode.

    摘要: A solid electrolyte probe for direct immersion into a molten material, such as molten copper, to determine the oxygen content thereof. A tubular receptacle fabricated from a solid electrolyte, such as stabilized zirconia, and adapted to hold an oxygen-containing material, has its open upper end protectively closed by a vertically elongate, relatively massive, refractory cap which has a longitudinal passage therethrough to accommodate the electrical lead for the probe electrode and is long enough to protect the tubular receptacle against both unrepresentative, high-oxygen molten material and the molten material-air interface, and to protect both the tubular receptacle and the electrical conductor against splash of the molten material that could otherwise lead to short circuiting of the electrical signals.
