Notes:
Processing of sealing materials is a key technology in planar SOFC. In this paper, compositionsof sealing materials were determined and then mixed and milled for 7~8 h. Glass materials were obtainedby melt at 1300 ~ 1600°C and quenched in cold water. The powder materials were made by milling andscreening. Properties of thermal expansion of sealing materials were on the same level to both electrolyteand interconnect. Experiments using 7 kinds of materials were carried respectively at 900°C and 1300°C.The most suitable sealing temperatures related to sealing materials were then determined. Thermal cycleexperiments were carried and hermetical properties were tested by red-absorption. Microstructure wereobserved with SEM and it revealed that the prepared sealing materials joins well with YSZ but not sogood with metal
