In chapter three the performance and structure of components of oxygen probe were especially investigated. The Cr-Cr〓O〓 powder was overcome by treatments. The reason of occurrence of thermal peaks on the EMF curves was explained. A water glass based cement which high temperature insulation was around 10MΩ within 10 seconds at 1600℃ was developed for the use of oxygen probe.
