Abstract：

At　present,　the　insufficient　thermo-mechanical　stability　of　sealing　glass　presents　a　challenge　for　solid　oxide　fuel　cells　(SOFCs).　In　this　work,　we　report　for　the　first　time　that　a　rigid-resilient　transition　occurs　in　a　calcium　borosilicate　sealing　glass　upon　heating　at　700　°C　for　different　durations.　The　elastic　modulus　increases　from　28.1–40.0　GPa　for　24　h　to　92.3–105.1　GPa　for　100　h,　while　the　corresponding　hardness　increases　from　2.5–3.1　GPa　to　8.1–9.2　GPa.　In　addition,　a　possible　mechanism　for　the　rigid-resilient　transition　has　been　proposed.　The　reported　results　provide　a　new　approach　to　solve　the　sealing　problem　of　SOFCs.　©　2018　Elsevier　Ltd
