A measuring probe for a measuring head to detect the oxygen activity of metal melts has a reference substance of known oxygen activity, which upon submersion into the metal melt is separated from the metal melt by means of a refractory solid electrolyte that conducts electrons reliably and conducts primarily oxygen at higher temperatures and which permits the measurement of the electromotive force between the reference substance and a bath contact which makes contact with the metal melt. The surface of the solid electrolyte is subjected to a surface cleaning treatment, primarily by means of etching.
In a process for the manufacture of a measuring probe for use in a measuring head to detect the oxygen activity of a metal melt, particularly a steel melt, and wherein said measuring probe is intended to be immersed in the metal melt, said process including providing a probe structure having a surface to contact the metal melt and formed of a solid refractory electrolyte material having the properties of conducting electrons reliably and conducting primarily oxygen at temperatures of the metal melt, the improvement comprising:
