摘要: The thermal properties, glass forming tendency and stability in solid oxide fuel cell (SOFC) relevant atmospheres have been determined for four different refractory MgO/CaO/Cr2O3–Al2O3–B2O3 phosphate based glasses. Also, the bonding ability interaction as a function of temperature between glasses La0.8Ca0.22CrO3 interconnect material studied. microstructural characterization elemental analysis reaction couples reveal that interface is closely related to CaO content relative tendency. reactions at 1000°C high or MgO containing compositions occur by liquid phase vapour mechanism, respectively. 1200°C both cases occurs mechanism. © 1998 Chapman & Hall
