X-ray diffraction investigations showed that these compounds are single-phase SrBi2Nb2-2xWxSnxO9 (x = 0.1, 0.2) and two-phase SrBi2Nb2-2xWxSnxO9 (x = 0.3, 0.4), but all of them had the structure of Aurivillius-Smolensky phases (ASPs) with close parameters of orthorhombic unit cells. It corresponded to the space group A21am. The temperature dependences of the relative permittivity \u03b5\/\u03b50 and the tangent of the dielectric loss angle tan d were defined at various frequencies. It was found that doping SrBi2Nb2-2xWxSnxO9 (x = 0.1) improved the electrophysical properties of the compound: losses decreased, and the relative permittivity increased. This result was obtained for the first time. Moreover, a new result was obtained that indicated an improvement in the electrophysical properties of SrBi2Nb2O9 using the chemical element Sn (tin). This refutes the previously existing opinion about the impossibility to use Sn as a doping element.<\/jats:p>","DOI":"10.3390\/ma17184455","type":"journal-article","created":{"date-parts":[[2024,9,11]],"date-time":"2024-09-11T02:34:49Z","timestamp":1726022089000},"page":"4455","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["New Piezoceramic SrBi2Nb2-2xWxSnxO9: Crystal Structure, Microstructure and Dielectric Properties"],"prefix":"10.3390","volume":"17","author":[{"given":"Sergei V.","family":"Zubkov","sequence":"first","affiliation":[{"name":"Research Institute of Physics, Southern Federal University, Rostov-on-Don 344090, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3833-0331","authenticated-orcid":false,"given":"Ivan A.","family":"Parinov","sequence":"additional","affiliation":[{"name":"I.
