The detailed steps for synthesizing zirconia by laboratory precipitation method are as follows:
Preparation of raw materials: Prepare the required zirconium salts and alkalis, such as zirconium nitrate and sodium hydroxide. These raw materials should be analytically pure to ensure that the synthesized zirconia has a high purity.
Preparation of zirconate precipitation: Mix zirconate and alkali in a certain stoichiometric ratio, and stir evenly. At this point, zirconium ions react with hydroxide ions to form zirconate precipitates. The chemical equation for this process is:
ZrCl4(aq) + 4NaOH(aq) → Zr(OH)4(s)+ 4NaCl (aq).
Filtering and washing: Use a vacuum pump and filter paper or centrifuge to filter out the precipitate, and wash repeatedly with deionized water to remove excess impurities. Be careful when washing to avoid sediment loss.
Oxidation treatment: Mix the filtered zirconate precipitate with an appropriate amount of oxidant (such as nitric acid, hydrogen peroxide, etc.), control the reaction temperature and time, and oxidize the zirconate to produce zirconia and water. The chemical equation for this process is:
Zr(OH)4(s) + 2HNO3(aq) → ZrO2(s) + 2H2O(l) + 2NO3-(aq).
Drying: After washing the product thoroughly, place it in an oven or dryer for drying to remove any moisture. When drying, temperature and time should be controlled to avoid decomposition or deformation of zirconia.
Grinding and screening: The dried zirconia can be ground and screened to ensure that its particle size and morphology meet the requirements of experiments or industrial applications.
