| | ZIRCONIUM DINITRATE OXIDE Usage And Synthesis |
| Acute toxicity | oral-rat LD50: 2500 mg/kg; intraperitoneal-rat LD50: 1250 mg/kg | | Storage | airtight, low temperature, dry | | Chemical Properties | White, hygroscopic crystals. Decomposes
at 100C. Soluble in water and alcohol. | | Uses | Zirconia nitrate is an important chemical raw materials, can be used as a reagent for the determination of potassium and fluoride, also used in the preparation of light agents and refractory materials, but also used in the preparation of catalysts, electronic products. | | Hazard | Dangerous fire and explosion risk in contact
with organics, strong oxidizing agent. | | Flammability and Explosibility | Non flammable | | Synthesis | (1) Take 10.0 kg of zirconium oxychloride, add 100 L of deionized water to dissolve, and prepare a 5 wt% ZrO 2 solution.
(2) Warm up to 70C, dropwise add 8.62kg 30wt liquid alkali to the salt solution in step (1), adjust the pH to 9.0, aging for 3h, leave overnight, solid-liquid separation.
(3) Add the filter cake obtained in step (2) to deionized water 80L pulping, add 36g ammonium nitrate, warm up to 75C and hold for 1h, solid-liquid separation. Repeat this step 3 times.
(4) Add the filter cake obtained in step (3) to deionized water 80L pulping, heating to 75 insulation 1h, solid-liquid separation. Repeat this step 1 time.
(5) The filter cake obtained in step (4) was pulped with 5283 g of 68 wt% concentrated nitric acid solution, warmed up to 75C and held for 4h, completely dissolved, and solid-liquid separation.
(6) The aqueous solution of zirconium nitroxide obtained in step (5), vacuum rotary evaporation for 8h, to obtain further concentrated aqueous solution of zirconium nitroxide.
