High　temperature　interactions　between　glass-ceramic　sealants　and　ferritic　interconnects　used　in　solid　oxide　fuel　cells　(SOFCs)　lead　to　the　formation　of　detrimental　chromate　phases,　such　as　BaCrO4　or　SrCrO4,　which　lead　to　the　mechanical　failure　of　the　cell.　In　present　work,　the　interactions　are　characterized　using　model　reactions　between　Cr2O3　and　glass　powders.　It　is　found　that　the　addition　of　MnO2　reduces　the　formation　of　SrCrO4　more　significantly　than　that　of　ZnO　and　La2O3,　in　the　SOFCs　operational　temperature　range　(e.g.,　900　°C).　In　addition,　the　mechanism　of　the　reduction　of　the　chromate　phase　by　different　additives　is　discussed　in　terms　of　the　possible　competing　reactions.　©　2010　Elsevier　B.V.　All　rights　reserved.
