The herein proposed synthetic procedure is advantageous in reducing energy consumption and processing time, key elements to decrease the total manufacturing cost. The as-prepared powder was calcined between 500 and 900 \u00b0C. Structure of the calcined powders, characterized by X-ray diffraction (XRD) and Rietveld refinement, indicated the formation of apatite crystalline lanthanum silicate with minor amount of L<jats:sub>2<\/jats:sub>O<jats:sub>3<\/jats:sub> at 900 \u00b0C. The apatite powder was further analyzed by scanning electron microscopy (SEM). The effect of sintering temperature, ranging from 1400 to 1450 \u00b0C, on the electrical properties was investigated by impedance spectroscopy. Electrical measurements were recorded in the 400 \u2013 800 \u00b0C temperature range. The lanthanum silicate electrolyte sintered at 1450 \u00b0C exhibited total electrical conductivity (\u03c3<jats:sub>700 \u00baC<\/jats:sub> = 2.12 x 10<jats:sup>-3<\/jats:sup> S.cm<jats:sup>-1<\/jats:sup>) comparable with samples from literature prepared by sol-gel and freeze drying methods and sintered at 1500 \u00b0C. The results in the present study demonstrate that the co-precipitation method combined with a sol-gel approach is a promising alternative route to synthesize lanthanum silicate powders.<\/jats:p>","DOI":"10.1149\/06136.0023ecst","type":"journal-article","created":{"date-parts":[[2014,10,3]],"date-time":"2014-10-03T04:46:04Z","timestamp":1412311564000},"page":"23-31","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Electrical Properties of Lanthanum Silicate Apatite Electrolytes Prepared by an Innovative Chemical Route"],"prefix":"10.1149","volume":"61","author":[{"given":"Graziele Lopes","family":"Macedo","sequence":"first","affiliation":[]},{"given":"Daniel Araujo","family":"Macedo","sequence":"additional","affiliation":[]},{"given":"S","family":"Rajesh","sequence":"additional","affiliation":[]},{"given":"Antonio Eduardo","family":"Martinelli","sequence":"additional","affiliation":[]},{"given":"Filipe M","family":"Figueiredo","sequence":"additional","affiliation":[]},{"given":"Fernando","family":"Marques","sequence":"additional","affiliation":[]},{"given":"Rubens Maribondo","family":"Nascimento","sequence":"additional","affiliation":[]}],"member":"77","container-title":["ECS Transactions"],"original-title":[],"link":[{"URL":"https:\/\/iopscience.iop.org\/article\/10.1149\/06136.0023ecst","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/iopscience.iop.org\/article\/10.1149\/06136.0023ecst\/pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/iopscience.iop.org\/article\/10.1149\/06136.0023ecst\/pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1149\/06136.0023ecst","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"},{"URL":"https:\/\/iopscience.iop.org\/article\/10.1149\/06136.0023ecst\/pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,1,15]],"date-time":"2022-01-15T00:27:32Z","timestamp":1642206452000},"score":1,"resource":{"primary":{"URL":"https:\/\/iopscience.iop.org\/article\/10.1149\/06136.0023ecst"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,9,29]]},"references-count":0,"journal-issue":{"issue":"36","published-print":{"date-parts":[[2014,9,29]]}},"URL":"https:\/\/doi.org\/10.1149\/06136.0023ecst","relation":{},"ISSN":["1938-5862","1938-6737"],"issn-type":[{"type":"print","value":"1938-5862"},{"type":"electronic","value":"1938-6737"}],"subject":[],"published":{"date-parts":[[2014,9,29]]},"assertion":[{"value":"Electrical Properties of Lanthanum Silicate Apatite Electrolytes Prepared by an Innovative Chemical Route","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 2014 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"}}]}}
