    摘要: In a solid-oxide fuel cell assembly comprising a plurality of components having electrically-conductive mating surfaces therebetween, the surfaces are sealed by an electrically insulating gasket that include a mineral composition comprising about 66 mol % MgO and about 33 mol % SiO2, the mineral composition being known mineralogically as forsterite. A brazing alloy may be applied to enhance bonding of the gasket into place. The gasket composition may include additions of Al2O3 to enhance electrical resistivity while having little to no impact of matching expansion coefficients of the gasket and metal mating surfaces. Also, additions such as titania or zirconia to inhibit glassy phase grain boundaries and the formation of impurities and pores in the ceramic grain boundaries may be used. A recommended particle size distribution of precursor powders is disclosed that leads to an optimum microstructure of the sintered gasket.
