Yttrium-Doped Barium Zirconate Powders Synthesized by the Gel-Casting Method
BaZr0.9Y0.1O2.95 powders were synthesized using both gel-casting process and solid-state reaction. The gel-casting process with citric acid as the complexing agent could result in nanoparticles with a single perovskite phase. Lower calcining temperature and shorter holding time were required to synthesize the BaZr0.9Y0.1O2.95 powders than the traditional solid-state reaction method. The work demonstrates that the gel-casting process is a simple, fast, and convenient method for preparing a high-temperature proton conductor BaZr0.9Y0.1O2.95 powder.
