Monopotassium phosphate (also, potassium dihydrogenphosphate, KDP, or monobasic potassium phosphate) is the inorganic compound. Together with dipotassium phosphate it is often used as a fertilizer, food additive, and buffering agent. The salt often cocrystallizes with the dipotassium salt as well as with phosphoric acid.
Single crystals are paraelectric at room temperature. At temperatures below −150 °C (−238 °F), they become ferroelectric.
Usage of Monopotassium Phosphate:
Manufacturing, Agriculture, Food and other.
Monopotassium phosphate is produced by the action of phosphoric acid on potassium carbonate.
Potassium phosphate monobasic; Phosphoric acid, monopotassium salt; Potassium biphosphate
