Ammonothermal preparation of barium zirconate fine powders
Barium zirconate fine powders of pure cubic phase were readily prepared from the reactions between BaCl2 2H2O and ZrOCl 2 8H2O under ammonothermal conditions at a very low temperature of 130°C as the lowest. KOH concentration was important in determining phase formation and particle morphology. Reac...

| Summary: | Barium zirconate fine powders of pure cubic phase were readily prepared from the reactions between BaCl2 2H2O and ZrOCl 2 8H2O under ammonothermal conditions at a very low temperature of 130°C as the lowest. KOH concentration was important in determining phase formation and particle morphology. Reaction temperature and time showed influences on the evolution of particle morphology and aggregation formation, respectively. Sizes of the primary particles critically depended on the BaII:ZrIV mole ratio. Phase formation mechanism is suggested. © 2008 Trans Tech Publications, Switzerland. |
