Using　an　Y(NO3)3　solution　as　a　liquid　medium,　an　Fe2O3-doped　8YSZ　(8　mol%　yttria-stabilized　zirconia)　electrolyte　can　be　fabricated　by　a　cold　sintering　process　(CSP)　and　a　conventional　sintering　(CS)　at　1100　°C,　and　a　relative　density　of　more　than　95%　can　be　achieved.　The　phase　structure,　sintering　behaviour　and　electrical　properties　of　the　8YSZ　samples　were　investigated　in　this　study.　The　results　indicate　that　the　sinterability　of　the　8YSZ　electrolyte　can　be　enhanced　by　the　CSP.　Moreover,　the　formation　of　the　monoclinic　phase　originating　from　the　Fe2O3　dopant　was　greatly　suppressed　by　introducing　the　Y(NO3)3　solution　into　the　CSP,　which　greatly　improved　the　electrical　properties　(i.e.　the　ionic　conductivity)　of　the　8YSZ　electrolyte.　The　sintered　Fe2O3-doped　8YSZ　provides　support　for　the　fabrication　of　high-performance　solid　oxide　fuel　cells　(SOFCs)　in　a　convenient　and　energy-saving　way.　©　2020　Elsevier　Ltd　and　Techna　Group　S.r.l.
