| preparation | (1) take 10.0 of zirconium oxychloride, add 100L of deionized water to dissolve, prepare 5wt%ZrO 2 solution. (2) the temperature is raised to 70 ° C., 8.62kg 30wt of liquid alkali is added dropwise to the salt solution of step (1), the pH value is adjusted to 9.0, the mixture is aged for 3H, left standing overnight, and solid-liquid separation is carried out. (3) the filter cake obtained in step (2) is added with deionized water (80L) for beating, 36g of ammonium nitrate is added, and the temperature is raised to 75 ° C. For 1H for solid-liquid separation. Repeat this step 3 times. (4) the filter cake obtained in step (3) is added to deionized water (80L) and then heated to 75 ° C. For 1H for solid-liquid separation. Repeat this step 1 time. (5) the filter cake obtained in step (4) is slurried with 5283G of 68wt% concentrated nitric acid solution, heated to 75 °c for 4H, completely dissolved, and solid-liquid separation. (6) the zirconium oxynitrate aqueous solution obtained in step (5) was rotary evaporated under vacuum for 8H to obtain a further concentrated zirconium oxynitrate aqueous solution. |
