Synthesis of BaZrO₃ Powders by Hydrothermal Method from Reactive Precursors

Abstract:

In this study, pure and crystalline BaZrO3 powders are prepared by hydrothermal synthesis using of precursor of barium chloride and zirconium oxychloride. The influence of several synthesis parameters is studied. At high OH- concentration, it is possible to obtain the well-crystallized stoichiometric perovskite phase at relatively low temperature. In addition, We had prepared high purity powder took a mere 1h at 130oC. The phase and particle morphology of the product were characterized by the techniques such as XRD, SEM and chemical analyses. The results indicated that the morphology of grain corresponded to rhombic dodecahedron, and the product had a particle size region which is 2~5µm.
