This study concerns two kinds of solid electrolytes for the sulfur sensor and SOx sensor, which enable instantaneous measurements of the amount of change of sulfur and of SOx concentration near the source in many industrial processes.The sulfur concentration cell was prepared with use of 95CaS-5Na_2S solid solution as the sulfur solid electrolyte and the electromotive force (EMF) of the cell was measured. The values obtained from the EMF measurement are close to the theoretical values calculated from the Nernst equation, therefore the ionic transference number of this solid solution is unity.The SOx concentration cell was also made with use of crystallized 33.9Li_2O-33.9B_2O_3-29Li_2SO_4-3.2Al_2O_3 as the solid electrolyte. From the results of the EMF measurement, it is concluded that the crystal phase of the solid electrolyte is an ionic conductor and the ionic transference number is also 1.

本研究涉及用于硫传感器和 SOx 传感器的两种固体电解质，这使得能够在许多工业过程中瞬时测量硫的变化量和源附近的 SOx 浓度。硫浓差电池是使用 95CaS- 制备的。 5Na_2S固溶体作为硫固体电解质并测量电池的电动势(EMF)。 EMF测量值与Nernst方程计算的理论值接近，因此该固溶体的离子迁移数是统一的。SOx浓差电池也是用结晶33.9Li_2O-33.9B_2O_3-29Li_2SO_4-制成的。 3.2Al_2O_3为固体电解质。从EMF测量结果可以看出，固体电解质的晶相是离子导体，离子迁移数也为1。
