20.500.12556/DiRROS-28631 Study of thermal decomposition of ▫$(Ba_{0.7}Ca_{0.3})TiO_3 and Ba(Zr_{0.2}Ti_{0.8})O_3$▫ xerogels and thin films Understanding the thermal decomposition and perovskite phase crystallization enables the design of the desired microstructure of BaTiO3-based thin films prepared by chemical solution deposition. We prepared xerogels from (Ba0.7Ca0.3)TiO3 (BCT) and Ba(Zr0.2Ti0.8)O3 (BZT) coating solutions, as well as BCT and BZT thin films, to investigate their thermal decomposition. The oxycarbonates, formed during the heating of BCT and BZT xerogels, are fully decomposed at 780 °C and 720 °C, respectively. The thermal decomposition of carbonate residues in BCT and BZT thin films is completed at 750 °C and 700 °C, respectively. The approximately 120 nm thick BCT and BZT films annealed at 850 °C crystallize in the perovskite phase. Razumevanje termičnega razpada in kristalizacije perovskitne faze omogoča načrtovanje mikrostrukture tankih plasti na osnovi BaTiO3, pripravljenih s sintezo v raztopini. Iz raztopin prekurzorjev (Ba0.7Ca0.3)TiO3 (BCT) in Ba(Zr0.2Ti0.8)O3 (BZT) smo pripravili ustrezna kserogela s sušenjem pri 200 °C in tanke plasti BCT in BZT z nanašanjem na podlage z metodo vrtenja. Termični razpad organskih skupin v kserogelih poteče preko oksikarbonatnih skupin, ki razpadejo šele po segrevanju pri temperaturah 780 °C (BCT) oziroma 720 °C (BZT). V tankih plasteh BCT in BZT po segrevanju pri 750 °C oziroma 700 °C na zaznamo več sledov ogljikovih faz. Približno 120 nm debele plasti BCT in BZT kristalizirajo v perovskitni fazi po segrevanju pri 850 °C. thermal decomposition thin films xerogels termični razpad tanke plasti kserogeli true false true Slovensko kemijsko društvo Slovenija Angleški jezik Slovenski jezik Copyright (c) 2026 Sabi William Konsago, Dean Birmančević, Jena Cilenšek, Brigita Kmet, Katarina Žiberna, Barbara Malič Neznano 2026-03-26 13:56:26 2026-03-26 13:56:27 2026-03-28 03:53:12 0000-00-00 00:00:00 2026 0 0 Nasl. z nasl. zaslona; Opis vira z dne 23. 3. 2026; str. 54-61 no. 1 Vol. 73 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2025-11-08 0000-00-00 2026-02-22 620.1/.2 1580-3155 10.17344/acsi.2025.9607 273144579 https://acsi-journal.eu/index.php/ACSi/article/view/9607 1 3595e171-2913-11f1-aa40-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=42541 RAZ_Konsago_Sabi_William_2026.pdf RAZ_Konsago_Sabi_William_2026.pdf 1 6B4A097437939B56FE580BDE306A628C 9d5f2ff4b98685ca59879f439b47cd14afa92d762b4f095351b959416ac50c9f 798abcbf-2913-11f1-aa40-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=42542 Institut Jožef Stefan 0 0 0
