摘要：

EMF sensor measurements using ZrO2(CaO) or ThO2(Y2O3) plug-type sensors with a Cr-Cr2O3 reference were performed to redetermine the Mn-O equilibrium reaction. In these experiments a strong effect of deoxidation of manganese was ascertained at saturation with solid deoxidation products. The measuring interval of the sensors at MnO saturation was invited to about 12 min due to chemical corrosion of the used Al2O3 sheaths. In the case of double saturation with solid MnO . Al2O3 (A) the sensors could be used as long as desirable. Moreover, the combined deoxidation of the iron melt with Mn and Al was investigated. An auxiliary electrode at the tip of the sensor ensured rapid saturation of the iron melt with solid MnO or MnO . Al2O3 + Al2O3.
