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. The effects of tip end thickness of ZrO〓 tube and amount of reference electrode on response time and thermal equilibrium in oxygen probe were investigated. The optimum tip end thickness of ZrO〓 tube and amount of reference electrode addition were determined. It is found that the heat transfer in oxygen galvanic cell is the rate limiting-step in the response process. The national oxygen probe WOS Ⅱ type was designed and manufactured. By three batches of industrial tests its specification reached the level of American Celox Ⅱ type oxygen probe.
