| titleOfInvention | Method for preparing urea ardealite by solution crystallization method taking ardealite as raw material |
| abstract | The invention discloses a method for preparing urea ardealite by a solution crystallization method taking ardealite as raw material. The method comprises the following steps of: (1) preparing a saturated urea aqueous solution, and adding ardealite, soluble phosphate and urea into the saturated urea aqueous solution to form slurry; (2) in the conditions of normal pressure and normal temperature, uniformly mixing the slurry and performing crystallization reaction to obtain urea ardealite slurry; and (3) performing solid-liquid separation on the urea ardealite slurry, and then drying the solid phase to obtain the urea ardealite. According to the invention, on the conditions of normal pressure and normal temperature, ardealite, soluble phosphate and urea are used as raw materials, a solution crystallization method is adopted, the investment is small, and the operation is convenient; and the prepared urea ardealite has the characteristics of regular crystal form, uniform granularity, accurate adjustment of purity and stable quality. |
