氧化锆固体电解质定氧测头氧电势的稳定性研究

EMF STABILITY OF THE ZIRCONIA SOLID ELECTROLYTE OXYGEN SENSOR

利用氧化镁部分稳定氧化锆作为钢液直接定氧测头的固体电解质，采用双测头比较方法研究了定氧测头氧电势的稳定性。所制备的氧化镁部分稳定氧化锆固体电解质直接定氧测头具有较好的稳定性和重现性。氧化锆固体电解质材料壁厚的不均匀缺陷是造成稳定性差的重要因素。

In the paper the EMF stability of the oxygen sensor using MgO partially stabilized zirconia solid electrolyte has been studied by the couple oxygen cells probe. It is found that the oxygen sensor in this work has good EMF stability.
