In particular, Ba0.85Ca0.15Zr0.10Ti0.90O3 (BCZT) and BaTi0.89Sn0.11O3 (BTSn) ceramics are among the best-studied lead-free BaTiO3-based ferroelectrics with high piezoelectric and electrocaloric properties. In this work, we prepared a 0.6BCZT–0.4BTSn solid solution. The structural, energy storage, electrocaloric, and pyroelectric properties are investigated. An energy density of 61.4 mJ cm-3 with a high energy efficiency of 82.4 % at 90 °C is achieved. The electrocaloric temperature change, which is determined indirectly via the Maxwell relation, is 0.5 K at 86 °C and 25 kV cm-1. It is stable over a wide temperature range of around 65 °C and has a coefficient of performance of 15. Moreover, a pyroelectric energy density of 124.1 mJ cm-3 is achieved. The results of this study show that the 0.6BCZT–0.4BTSn ceramics is a multifunctional material with energy storage, electrocaloric and pyroelectric properties. Feroelektrični materiali pridobivajo veliko pozornost v raziskavah, ki se osredotočajo na elektrokalorične in piroelektrične pojave ter na shranjevanje energije. Zlasti keramiki Ba0.85Ca0.15Zr0.10Ti0.90O3 (BCZT) in BaTi0.89Sn0.11O3 (BTSn) sodita med najbolj raziskane keramične materiale brez svinca na osnovi BaTiO3 . V tem delu smo pripravili trdno raztopino 0.6BCZT–0.4BTSn. Raziskali smo strukturne, elektrokalorične in piroelektrične lastnosti keramike 0.6BCZT-0.4BTSn ter njeno zmožnost shranjevanja energije. Keramika izkazuje gostoto shranjevanja energije v višini 61.4 mJ cm-3 z najvišjim energijskim izkoristkom 82.4 % pri temperaturi 90 °C. Elektrokalorična temperaturna sprememba določena preko Maxwellove enačbe, znaša 0.5 K pri temperature 86 °C in električnem polju 25 kV cm-1 ter je stabilna v širokem temperaturnem območju 65 °C s koeficientom učinkovitosti 15. Keramika izkazuje tudi piroelektrično gostoto energije 124.1 mJ cm-3. Rezultati kažejo, da je keramika 0.6BCZT-0.4BTSn večfunkcijski material, ki izkazuje elektrokalorične in piroelektrične lastnosti ter zmožnost shranjevanja energije. electronic ceramics lead-free ceramics energy storage energy harvesting pyroelectric electrocaloric elektronska keramika keramika brez svinca shranjevanje energije elektrokalorik piroelektrik zbiranje energije true false false Angleški jezik Slovenski jezik Neznano 2026-06-09 08:03:17 2026-06-18 06:06:58 2026-06-19 03:51:33 0000-00-00 00:00:00 2024 0 0 Besedilo v angl.; Soavtorji iz Slovenije: Zouhair Hanani, Hana Uršič, Uroš Prah, Matjaž Spreitzer, Brigita Rožič, Zdravko Kutnjak; str. 237-245 no. 4 Vol. 54 Dec. 2024 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 2024-12-01 544.5/.6 0352-9045 10.33180/InfMIDEM2024.401 218042115 https://ojs.midem-drustvo.si/index.php/InfMIDEM/article/view/1943 1 e954a241-63c8-11f1-9215-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=44930 https://www.midem-drustvo.si/journal_papers/MIDEM_54(2024)4p1.pdf 1 bc86e966-63ca-11f1-9215-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=44967 https://www.midem-drustvo.si/journal_papers/MIDEM_54(2024)4p1.pdf 1 58b342c6-63d4-11f1-9215-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=45033 https://plus.cobiss.net/cobiss/si/sl/data/cobib/218042115 1 f81347fd-63c8-11f1-9215-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=44942 https://ojs.midem-drustvo.si/index.php/InfMIDEM/article/view/1943 1 2779daef-6acb-11f1-a3b9-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=45853 Strokovno društvo za mikroelektroniko, elektronske sestavne dele in materiale 0 0 0
