| Abstract: | A sulphur sensor was developed using MgS+TiS_2 solid electrolyte with Mo+MoS_2 taken as reference electrode, and it was applied to determining the sulphur content in liquid carbon-saturated iron at 1623K in lab through EMF measurement. Further, the problem of gas leakage and burst of solid electrolyte tubes were solved by optimizing the construction of those tubes, and the hydration and oxidation of the sulphide were also avoided by special processes. The results showed that the sulphur sensor could be continuously used with stable EMF signals and good reproducibility provided. |
