This study examines the influence of pH on the development of zirconia from zirconium(IV) acetate solutions, utilizing both boiling under reflux and hydrothermal processing methods. The synthesized gels and powders were calcined at varying temperatures and analyzed through X-ray powder diffraction and Raman spectroscopy. This research finds that Raman spectroscopy is particularly effective in distinguishing between tetragonal and cubic zirconia phases. Results indicate that zirconia produced from higher pH solutions favors the tetragonal polymorph, suggesting that increased alkalinity enhances the stability of this form alongside monoclinic zirconia. Additionally, the hydrothermal method at high pressures predominantly yields monoclinic zirconia under acidic conditions. The study concludes that the pH of the initial reaction mixture significantly affects the polymorphic outcome of zirconia formation, with implications for material properties and processing techniques.
