The as\u2010synthesized powder material was calcined at 700 \u00b0C for 2 h, with X\u2010ray diffraction revealing a single cubic phase with lattice parameter a = 0.5435 nm and theoretical density of 7.144 gcm<jats:sup>\u20103<\/jats:sup>. The average crystallite size is 12 nm, as determined by the Scherrer equation. Impedance spectroscopy revealed a larger resistive contribution of the grain boundaries than that from grain bulk, which, due to its lower activation energy, tends to dominate the total conductivity above 650 \u00b0C. The total conductivity is in line with literature data for ceramics of the same composition prepared by various methods, thus confirming the potential of the proteic sol\u2010gel method as a green, low cost alternative synthetic route to prepare ceria\u2010based solid electrolytes.<\/jats:p>","DOI":"10.1002\/crat.201600052","type":"journal-article","created":{"date-parts":[[2016,6,16]],"date-time":"2016-06-16T15:51:31Z","timestamp":1466092291000},"page":"400-404","source":"Crossref","is-referenced-by-count":13,"title":["Synthesis of Ce<sub>0.8<\/sub>Sm<sub>0.2<\/sub>O<sub>1.9<\/sub> solid electrolyte by a proteic sol\u2010gel green method"],"prefix":"10.1002","volume":"51","author":[{"given":"Daniel A.","family":"Macedo","sequence":"first","affiliation":[{"name":"Materials Science and Engineering Postgraduate Program UFPB  58051\u2010900 Jo\u00e3o Pessoa Brazil"}]},{"given":"Ricardo P.
