摘要 在地球科学实验中,氧逸度、氢逸度是反映待测体系的氧化还原状态和制约体系发展过程的重要参数。本文阐述了钇稳定氧化锆(YSZ)的导电机理和不同稳定剂(Y2O3)掺杂量对性质的影响,并列举了实验地球化学中利用YSZ传感器测定体系氧逸度、氢逸度及pH值的方法。与已有的其他氧/氢逸度测量方法相比较,YSZ传感器在实验中有耐高温、高压、抗腐蚀性强、响应快、原位测定特性好等诸多优点。最后指出了YSZ在应用于实验过程中的存在问题。随着陶瓷制作技术、微机械加工技术和微电子技术的发展,YSZ在地学实验中的应用将更加多样化和具有针对性。 Given the great significance of oxygen fugacity and hydrogen fugacity in geoscience experiments, numerous efforts have been made by scientists to measure them. In this paper, electric conduction mechanisms of Yttria Sta- bilized Zirconia (YSZ) and influences of different stabilizing agent contents to the nature of YSZ were described, and applications of YSZ sensor in measuring oxygen fugacity, hydrogen fugacity and pH value of experimental geo- chemistry systems were summarized. Comparing with other methods of measuring oxygen fugacity and hydrogen fugacity, YSZ oxygen sensor is applicable to high-temperature, high-pressure and crrossive systems. In addition, YSZ oxygen sensor has advantages of quick-response and in-situ measuring in geochemistry experiments. In later of the paper, some problems of YSZ applications in goescience were discussed. Authors believe that applications of YSZ in geology experiments will be more diversified as well as more specified when the development of ceramics manufacture, micro mechanical manufacture and micro-electronics technology is going.
