The　chemical　compatibility　of　sealing　glass　is　of　great　importance　for　Solid　oxide　fuel　cell　(SOFC).　In　this　work,　the　interfacial　reaction　between　sealing　glass　and　Cr-containing　interconnect　alloy　is　characterized　by　reacting　Cr2O3　powders　with　a　representative　SrO-containing　glass　crystallized　by　different　heat-treatment　schedules.　The　crystalline　structure　and　crystalline　content　of　sealing　glass　are　determined　by　X-ray　diffraction.　The　results　show　that　the　fraction　of　Cr6+　decreases　from　39.8　±　1.9%　for　quenched　glass　to　8.2　±　0.4%　for　glass　crystallized　at　900　°C　for　2　h.　In　addition,　the　interfacial　reaction　can　be　further　reduced　with　increasing　crystallization　temperature　and　time　as　well　as　the　addition　of　nucleation　agent　(TiO2).　The　formation　of　some　Sr-containing　crystalline　phases,　Sr2SiO4　and　Sr(TiO3),　contributes　to　the　improvement　of　chemical　compatibility　of　sealing　glass,　in　agreement　with　the　results　of　thermodynamic　calculations.　©　2012　Elsevier　B.V.
