Chemical stability of MgO/CaO/Cr2O3–Al2O3

The thermal properties glass forming tendency and glass 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 and interaction as a function of temperature between the glasses and La0.8Ca0.22CrO3 interconnect material have been studied.

Stresses in NiO Cr2O3 and Al2O3 oxide scales Semantic

Stresses in NiO Cr2O3 and Al2O3 oxide scales. Abstract The protective character of oxide scales developed at high temperature on metallic alloys strongly depends on the adherence of the scales which must be related to the stress level in the scales. Thus after a review of the origins of the stresses in such scales the methods actually used
