Potassium Dihydrogen Phosphate (chemical formula KH2PO4) is a high concentration phosphorus potassium compound fertilizer, white granular crystal, soluble in water, slightly soluble in alcohol, insoluble in acetone. Stable in the air, a small amount of decomposition at 100 ° C, solid relative density of 1.803(19 ° C), melting point of 190 ° C. The loss of ammonia and water beyond the melting point produces a mixture of ammonium metaphosphate and phosphoric acid. A 1% aqueous solution has a PH of 4.5. The P2O5 content is 52% and the K20 content is 34%. Low moisture absorption, good physical properties, easy to dissolve in water, 20ºC per 100 ml water contains 23g, the aqueous solution is acidic.
