Abstract

Barium cerate, BaCeO₃, powders and films were produced from sol-gel precursors. The formation of BaCeO₃ was achieved by calcining the sol-gel precursors either at 800°C overnight or at 1000°C for an hour, in contrast to 1400°C overnight in convectional solid-state preparation. Films with (200) preferred orientations were obtained on SrTiO₃(100) single-crystal substrates. Sol-gel precursor solution was also used to produce cerium zirconium oxide, Ce_0.75Zr_0.25O₂, at temperatures as low as 400°C. The Ce_0.75Zr_0.25O₂ so generated showed no structural change on heating up to 1100°C. The Ce_0.75Zr_0.25O₂ films produced were polycrystalline.
