The results show that with an increase in the Nd2O3 doping amount, the grain size of the ceramics was reduced from 2.93 \u03bcm to 0.69 \u03bcm. The hardness and strength of the ceramics increased significantly, while the fracture toughness decreased. The reduction in fracture toughness was attributed to the reduction in tetragonal grain size, which suppressed the tetragonal\u2013monoclinic phase transformation caused by stress. Additionally, as the content of Nd2O3 increased, the formation of cubic zirconia accelerated, but no second phase was observed. Most importantly, when the doping amount of Nd2O3 reached 0.3 mol%, the comprehensive mechanical characteristics of the ceramics were optimal. This provides a research basis for the preparation of nanoscale 12 mol% ceria-stabilized tetragonal zirconia polycrystal ceramics.<\/jats:p>","DOI":"10.3390\/ma17225426","type":"journal-article","created":{"date-parts":[[2024,11,6]],"date-time":"2024-11-06T11:13:37Z","timestamp":1730891617000},"page":"5426","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Improving the Mechanical Properties and Microstructure of 12 mol% Ceria-Stabilized Tetragonal Zirconia Polycrystal Ceramics with Low-Content Nd2O3"],"prefix":"10.3390","volume":"17","author":[{"given":"Zengqing","family":"Sun","sequence":"first","affiliation":[{"name":"School of Minerals Processing & Bioengineering, Central South University, Changsha 410083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaoyu","family":"Li","sequence":"additional","affiliation":[{"name":"School of Minerals Processing & Bioengineering, Central South University, Changsha 410083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9746-1393","authenticated-orcid":false,"given":"Jinxin","family":"Xing","sequence":"additional","affiliation":[{"name":"School of Minerals Processing & Bioengineering, Central South University, Changsha 410083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Min","family":"Gan","sequence":"additional","affiliation":[{"name":"School of Minerals Processing & Bioengineering, Central South University, Changsha 410083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhiyun","family":"Ji","sequence":"additional","affiliation":[{"name":"School of Minerals Processing & Bioengineering, Central South University, Changsha 410083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yong","family":"Lyu","sequence":"additional","affiliation":[{"name":"School of Metallurgical and Ecological Engineering, University of Science and Technology Beijing, Beijing 100083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,11,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Andrea, L., Teodoro, K., \u017deljko, S., Marko, J., and Mark, \u017d.
