abstract Diopside (CaMgSi2O6) based glasses compositions containing magnesium orthosilicate or barium aluminosilicates phases have been appraised for sealing applications in solid oxide fuel cells (SOFCs) and other solid-electrolyte devices. The sintering behavior and crystalline phase evolution of glass powders has been investigated under isothermal and non-isothermal conditions in the SOFC operating temperature range (800-900 degrees C). All the glass compositions exhibited two-stage shrinkage behavior resulting in well sintered and mechanically strong glass-ceramics with Augite as the primary crystalline phase. The appropriate coefficient of thermal expansion (CTE), long term thermal stability (300 h at 900 degrees C), high electrical resistivity, good adhesion and minimal reactivity with SOFC components makes the investigated glass-ceramics potential candidates for further experimentation as SOFC sealants.
