| 摘 要： | 采用以ZrO_2(MgO)固体电解质,配以一新辅助电极SiO_2+CaF_2的方法,对Fe+C(sat)+Si体系进行了测量。结果表明:当硅测头插入铁水5s以后电动势值即可达到稳定值;电动势与硅量的关系符合理论公式;T=1694～1749K,电动势随温度的变很小。本研究所开发的硅测头具有响应迅速、准确,可望在现场得到应用推广。

| Abstract: | Laboratory EMF measurements were conducted in Fe+C(sat) +Si system using ZrO2 (MgO) solid electrolyte equipped with a new auxiliary electrode SiO2+CaF2. The results showed that the measured EMFs reaches stable value within 5 seconds after immersion of the developed silicon probe into the above melt; the relation between measured EMFs and silicon activity corresponds with the theoretical calculation; the measured EMFs were nearly independent of measured temperature from 1 694 to 1 749K. Due to the rapid response and accuracy of the silicon probe developed in this study, it is expected to be used in situ. |
