    Abstract

    Sulfur in steel is one of the most important deleterious element, so monitoring sulfur content is important to improve the quality of steel products. Solid electrolyte based sensors are well suited to metallurgical processes. However, the design of effective high temperature electrochemical sulfur sensors requires higher stability of sulfides and strategic combinations of electrolyte and auxiliary electrode materials to provide satisfactory response and stability. The approaches and materials used in the development of sulfur sensor are reviewed, and theoretical sulfur activity versus potential relation is given in this paper.
