Samples sintered between 1350 and 1450 \u00b0C had their microstructures and electrical properties investigated by scanning electron microscopy (SEM) and impedance spectroscopy. The total electrical conductivity in the range of 100 \u2013 500 \u00b0C of one-step composites is more than one order of magnitude higher than for conventional material. This result is associated to the presence of a network of well-connected and homogeneously distributed NiO grains shown by SEM for the one-step composite, which is responsible for its improved percolative behavior and lower activation energy (0.24 eV at 250 \u2013 650 \u00b0C).<\/jats:p>","DOI":"10.1149\/05022.0021ecst","type":"journal-article","created":{"date-parts":[[2013,4,23]],"date-time":"2013-04-23T15:15:25Z","timestamp":1366730125000},"page":"21-31","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Electrical Conductivity and Microstructure of NiO-CGO Composites Prepared By One-Step Synthesis"],"prefix":"10.1149","volume":"50","author":[{"given":"Daniel Ara\u00fajo de","family":"Macedo","sequence":"first","affiliation":[]},{"given":"Filipe M.L.","family":"Figueiredo","sequence":"additional","affiliation":[]},{"given":"S\u00f3nia G.","family":"Patr\u00edcio","sequence":"additional","affiliation":[]},{"given":"Rubens M.","family":"Nascimento","sequence":"additional","affiliation":[]},{"given":"Antonio Eduardo","family":"Martinelli","sequence":"additional","affiliation":[]},{"given":"Carlos A.","family":"Paskocimas","sequence":"additional","affiliation":[]},{"given":"Fernando M.B.","family":"Marques","sequence":"additional","affiliation":[]}],"member":"77","container-title":["ECS Transactions"],"original-title":[],"link":[{"URL":"https:\/\/iopscience.iop.org\/article\/10.1149\/05022.0021ecst","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/iopscience.iop.org\/article\/10.1149\/05022.0021ecst\/pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/iopscience.iop.org\/article\/10.1149\/05022.0021ecst\/pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1149\/05022.0021ecst","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"},{"URL":"https:\/\/iopscience.iop.org\/article\/10.1149\/05022.0021ecst\/pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,2,8]],"date-time":"2022-02-08T01:41:07Z","timestamp":1644284467000},"score":1,"resource":{"primary":{"URL":"https:\/\/iopscience.iop.org\/article\/10.1149\/05022.0021ecst"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,4,1]]},"references-count":0,"journal-issue":{"issue":"22","published-print":{"date-parts":[[2013,4,1]]}},"URL":"https:\/\/doi.org\/10.1149\/05022.0021ecst","relation":{},"ISSN":["1938-5862","1938-6737"],"issn-type":[{"value":"1938-5862","type":"print"},{"value":"1938-6737","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013,4,1]]},"assertion":[{"value":"Electrical Conductivity and Microstructure of NiO-CGO Composites Prepared By One-Step Synthesis","name":"article_title","label":"Article Title"},{"value":"ECS Transactions","name":"journal_title","label":"Journal Title"},{"value":"paper","name":"article_type","label":"Article Type"},{"value":"\u00a9 2013 ECS - The Electrochemical Society","name":"copyright_information","label":"Copyright Information"},{"name":"date_received","label":"Date Received","group":{"name":"publication_dates","label":"Publication dates"}},{"name":"date_accepted","label":"Date Accepted","group":{"name":"publication_dates","label":"Publication dates"}},{"name":"date_epub","label":"Online publication date","group":{"name":"publication_dates","label":"Publication dates"}}]}}
