In the meantime, many of the initial drawbacks of these materials compared to conventional lead titanate-zirconate (PZT) ceramics have been overcome. Today, industrial production of potassium-sodium niobate (KNN)-based ceramics has become a reality, applications have been identified and KNN-based products have been manufactured. While certain KNN compositions have achieved piezoelectric performance comparable to, or even exceeding, that of lead-based systems, persistent inconsistencies in the literature regarding the description of their crystalline structures underscore the need for a clearer understanding. This focused review critically examines the key factors shaping the crystal structure of KNN ceramics, with a particular emphasis on processing techniques as a pivotal parameter. The discussion is organized around three fundamental aspects: i) the crystal structure of pure KNN, ii) the structural modifications induced by additives, and iii) the influence of texturing processes on crystalline organization. Special attention is devoted to X-ray diffraction (XRD) characterization and the structure-property relationships that govern KNN\u2019s performance.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>You can now read the recently published article by ANTONIO IACOMINI, MARIA DORE, COSTANTINO CAU and LORENA PARDO. \u201cShaping the Crystal Structure and Piezoelectricity of Potassium Sodium Niobate: A Review\u00bb Materials Today Communications, 115936, (2026) DOI: 10.1016\/j.mtcomm.2026.115936 Abstract Research activities on lead-free piezoelectric ceramic materials have been ongoing for over&#8230;<\/p>\n<p class=\"continue-reading-button\"> <a class=\"continue-reading-link\" href=\"https:\/\/wp.icmm.csic.es\/mscg\/2026\/08\/25\/566\/\">Continue reading<i class=\"crycon-right-dir\"><\/i><\/a><\/p>\n","protected":false},"author":64,"featured_media":577,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-566","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-sin-categoria"],"_links":{"self":[{"href":"https:\/\/wp.icmm.csic.es\/mscg\/wp-json\/wp\/v2\/posts\/566","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wp.icmm.csic.es\/mscg\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/wp.icmm.csic.es\/mscg\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/wp.icmm.csic.es\/mscg\/wp-json\/wp\/v2\/users\/64"}],"replies":[{"embeddable":true,"href":"https:\/\/wp.icmm.csic.es\/mscg\/wp-json\/wp\/v2\/comments?post=566"}],"version-history":[{"count":6,"href":"https:\/\/wp.icmm.csic.es\/mscg\/wp-json\/wp\/v2\/posts\/566\/revisions"}],"predecessor-version":[{"id":579,"href":"https:\/\/wp.icmm.csic.es\/mscg\/wp-json\/wp\/v2\/posts\/566\/revisions\/579"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/wp.icmm.csic.es\/mscg\/wp-json\/wp\/v2\/media\/577"}],"wp:attachment":[{"href":"https:\/\/wp.icmm.csic.es\/mscg\/wp-json\/wp\/v2\/media?parent=566"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/wp.icmm.csic.es\/mscg\/wp-json\/wp\/v2\/categories?post=566"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/wp.icmm.csic.es\/mscg\/wp-json\/wp\/v2\/tags?post=566"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
