The high temperature chemical cell was used for determining sulfur content in carbon saturated liquid iron. The powder of ZrO 2 (Y 2O 3) was acted as solid electrolyte, and the mixture of Y 2O 3 and Y 2O 2S was acted as its auxiliary electrode of A type determining sulfur sensors. The mixture of ZrO 2 (Y 2O 3) and Y 2O 2S was used as solid electrolyte of B type determining sulfur sensors directly. The experimental results on measuring sulfur concentration in cast iron indicated that the signal of these two kinds of sensors are stable. The sensors have fast response, good reproducibility, long continuous time, and high accuracy. The sulfur content in the cast iron was obtained at 1 583 K.
