| Abstract: | The crystallization kinetics of potassium dihydrogen phosphate from wet-process phosphoric acid purified by crystallization of melamine phosphate was investigated. The effects on crystallization habit by agitation, vibration, impurity, cooling were studied. The crystallization kinetics equation was presented. The dehydration features of product KH_2PO_4 were determined. |
| Keywords: | potassium dihydrogen phosphate crystallization kinetics wet-process phosphoric acid |
