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.Slovensko kemijsko društvo20262026-03-26 13:56:26Neznano28631SlovenijaslCopyright (c) 2026 Sabi William Konsago, Dean Birmančević, Jena Cilenšek, Brigita Kmet, Katarina Žiberna, Barbara Malič
