    Electrochemical measurements of oxygen activity of glass melts in glass melting furnaces
    (Offenbach : Verlag der Deutschen Glastechnischen Gesellschaft, 1988) Müller-Simon, Hayo; Mergler, Kurt W.
    The electrochemical determination of the oxygen activity of a glass melt by a stabilized ZrO2 sensor was established as an online measurement in a working chamber and a feeder channel. A method is described to take the temperature difference between the sensor's electrodes into account. In green glass a correlation between the oxygen activity and Fe2+/Fetot ratio, in amber glass a correlation between oxygen activity and Cr2O3 content are found.

    Sensor for oxygen activity measurements in glass melts
    (Offenbach : Verlag der Deutschen Glastechnischen Gesellschaft, 1991) Müller-Simon, Hayo; Mergler, Kurt W.
    Traditional oxygen activity measurement in glass melts is based on Y2O3-stabilized ZrO2 which, in continuous use in the glassworks, is subjected to considerable wear. The present paper describes an oxygen sensor that is not equipped with wear parts. The new sensor is far less sensitive to temperature gradients in the surrounding area than ZrO2 sensors; the oxygen measurement, however, is greatly disturbed at direct flame irradiation.
