Abstract: | A novel method for zirconium oxide crystal synthesis from an aqueous solution at ordinary temperature and pressure has been discovered. Boric acid was added to a sodium hexafluorozirconate solution, fluoride ion was consumed by the formation of BF−4 complex ion, then the hexafluorozirconate ion was hydrolyzed to zirconium oxide in order to increase the amount of fluoride ion. The formation of zirconium oxide crystal was confirmed by clear X-ray diffraction peaks. This method is promising for preparing zirconium oxide films in various applications |
