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　degrees　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.　(c)　2012　Elsevier　B.V.　All　rights　reserved.
