An apparatus to determine partial electronic conduction parameter, Pe' , of solid electrolytes for oxygen sensor to determine oxygen contents in molten steel has been developed. Principle of the method has been based on 2 poles impedance method.The values determined by the apparatus are the same as that by swinkels method. Prominence futures of the apparatus are as follows; 1. Partial electronic conduction parameter of smaller size of solid electrolyte can be measured. 2. Measuring time is much shorter than that of swinkels method.The partial electronic conduction parameter of commercial grade solid electrolyte of ZrO_2-MgO has been measured by the apparatus. Measured results are as follows; 1. The smaller contents of MgO, the semller Pe'. 2. Different Pe' can be observed when solid electrolytes supplied by different manufacture were observed.

研制了测定钢水含氧量的氧传感器用固体电解质部分电导参数Pe‘的测定装置。该方法的原理是基于两极阻抗法，其测定值与斯温克尔斯法相同。该装置的突出特点如下：1.可以测量较小尺寸固体电解质的部分电导参数。2.测量时间远短于Swinkels法。用该装置测量了工业级固体电解质ZrO_2-MgO的部分电子电导参数。测试结果如下：1.氧化镁含量越小，Pe‘越小。2.观察不同厂家提供的固体电解质，可观察到不同的Pe‘。
