A flexible member capable of withstanding a high temperature environment and/or a corrosive atmosphere or media is formed of a component in a desired shape and of a ceramic material having a modulus of elasticity of 150,000 to 200,000 MPa and a flexural strength of more than 400 MPa. The component is provided with at least one reduced thickness portion to impart to the component a desired degree of flexibility and/or elasticity.

Flexible ceramic member and method of production thereof

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.
