[Nature] of potassium dihydrogen phosphate as white crystals, soluble in water, insoluble in alcohol, aqueous acidic reaction, 1% solution PH value of 4.5. The relative density of the solid is 2.338, a melting point of 252.6 ℃. Starts dehydration at 200 ℃, 240 ~ 260 ℃ change of the partial potassium (KPO3) phosphoric acid, heated to 400 ℃, the molten transparent liquid, solidified after cooling opaque glassy material (KPO3) n. [Uses] dihydrogen phosphate mainly used in the pharmaceutical and electronics industries, but also for the production of tripolyphosphate and potassium salts. In agriculture as a non-chlorine type P, K binary efficient fertilizer use (a lot of elements soluble fertilizer), the total nutrient (K2O + P2O5) was 86%, which is the preparation of N, P, K compound fertilizer, foliar The basic raw material for fertilizer, food industry for baking and food flavoring additives, food additives, fermentation industry as a bacterial culture agents, buffering agents regulators and nutrition. Sewage treatment is also used. [Packing] plastic woven bag, net weight 25KG or 50KG, stored in ventilated and dry place.
