In the present investigation, several glasses based on the BaO-CaO-Al2O3-SiO2 (BCAS) system have been investigated to see their applicability as IT-SOFC sealants. The glass transition temperature (Tg) of the developed glasses are within 600-6350C. The CTE value can be tailored between that of YSZ electrolyte and ferritic steel (FS) interconnect, by varying the amount of alkaline-earth metal content. The electrical resistivities of the developed glasses are quite high (rho 800C ~ 105 Omega-cm) and thus suitable for IT-SOFC application. Based on the crystallization behavior, a single glass having matching CTE with FS and a bi-layer glass having different CTE values within the range of 10×10-6 K-1 to 13×10-6 K-1 are found to be very effective for the FS-FS and FS-YSZ sealing.
