The resulting materials show a stable cubic fluorite structure with only minor traces of segregated manganese oxides and relative density from 90% to 98%. The linear thermal expansion coefficient is in the order of 10\u22125 K\u22121 at 500 K and increases gradually with temperature, due to the onset of a contribution of chemical expansion, reaching about 13 \u00d7 10\u22126 K\u22121 at 1100 K. These results are suitable for prospective applicability as buffer layers to minimize degradation and delamination of electrolyte\/oxygen electrode interfaces in solid electrolyte cells. The electrical conductivity remains close to 1 S\/m at 973 K and close to 7 S\/m at 1273 K, suggesting mixed conductivity with a prospective contribution to electrode processes occurring at electrode\/electrolyte interfaces. Guidelines for further improvement were also established by a detailed analysis of the impact of heating\/cooling rate, firing temperature, and time on those properties, based on Taguchi planning.<\/jats:p>","DOI":"10.3390\/ceramics3030031","type":"journal-article","created":{"date-parts":[[2020,9,9]],"date-time":"2020-09-09T09:01:09Z","timestamp":1599642069000},"page":"345-358","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Structural Design of 5 mol.% Yttria Partially Stabilized Zirconia (5Y-PSZ) by Addition of Manganese Oxide and Direct Firing"],"prefix":"10.3390","volume":"3","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5820-9865","authenticated-orcid":false,"given":"Alejandro","family":"Natoli","sequence":"first","affiliation":[{"name":"CICECO\u2014Aveiro Institute of Materials, Department of Materials and Ceramic Engineering, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3837-5946","authenticated-orcid":false,"given":"Aleksey","family":"Yaremchenko","sequence":"additional","affiliation":[{"name":"CICECO\u2014Aveiro Institute of Materials, Department of Materials and Ceramic Engineering, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8445-2562","authenticated-orcid":false,"given":"Jorge R.","family":"Frade","sequence":"additional","affiliation":[{"name":"CICECO\u2014Aveiro Institute of Materials, Department of Materials and Ceramic Engineering, University of Aveiro, 3810-193 Aveiro, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2020,9,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"730","DOI":"10.1021\/acsami.8b17062","article-title":"Defective MnxZr1\u2212xO2 solid solution for the catalytic oxidation of toluene: Insights into the oxygen vacancy contribution","volume":"11","author":"Yang","year":"2019","journal-title":"ACS Appl.
