High-temperature　interactions　between　glass-ceramic　sealants　and　Cr-containing　ferritic　interconnects　used　in　solid　oxide　fuel　cells　(SOFC)　lead　to　the　formation　of　detrimental　chromate　interfacial　phases,　such　as　BaCrO　4　or　SrCrO4,　which　can　cause　mechanical　failure　of　the　SOFC.　In　this　work,　these　interactions　are　characterized　by　reacting　Cr　2O3　powders　with　a　SrO-containing　sealing　glass　and　by　characterizing　representative　reaction　couples　between　the　glass　and　430　stainless　steel.　The　extent　of　chromate　formation　depends　on　the　reaction　time　and　temperature,　and　the　effect　of　the　partial　pressure　of　oxygen　is　modeled　by　thermochemical　calculations.　©　2012　Elsevier　B.V.　All　rights　reserved.
