Properties: white crystal or formless powder. It is soluble in water easily, slightly soluble in alcohol.Strong absorption of moisture.When anhydrous product heated to 204\u00b0C.It will be dehydrated into tetra potassium pyrophosphate. The PH of 1% aqueous solution is about 9.<\/p>\n\n\n\n Uses: Fertilizer<\/p>\n\n\n\n Used as a high efficient, K and P compound water soluble fertilizer, also as a basic raw material for NPK fertilizers. The raw material for producing potassium pyrophosphate.<\/p>\n\n\n\n Used for boiler water treatment. Used as a buffering agent in chemical analysis, for phosphating of metals, and as an additive in electroplating. Antifreeze, corrosion inhibitor, and phosphate potassium regulator for fermentation industry.<\/p>\n\n\n\n Used in the pharmaceutical industry as a culture agent for penicillin and streptomycin, as a nutrient for microorganisms, fungi, and antibiotic culture media. It can also be used as a de iron agent and pH regulator for talc powder.<\/p>\n\n\n\n The food industry uses alkaline water as a raw material, fermentation agent, seasoning agent, leavening agent, mild alkaline agent for dairy products, yeast feed, and sometimes it is added to milk tea powder. It can also be used as a feed additive.<\/p>\n\n\n\n Packing\uff1aPlastic woven bag.
