Product Description Product DescriptionMono Potassium Phosphate is an excellent potassium & phosphorus fertilizer. It is an inorganic compound. Appearance white crystal powder and it is easy to dissolve in water, the aqueous solution is slightly alkaline, slightly soluble in alcohol, and is hygroscopic and is autolysis at a high temperature. It is widely used in almost all types of crops, grain, melon and fruit, vegetables and so onPropertiesColorless crystals or white powder, with hygroscopy.Stable in the air, non-combustible.Becomes transparent liquid after heated to 400oC and solidified into non-transparent vitrescent potassium metaphosphate.Melting point is 252.6oC.Relative density is 2.238g/cm3.Solubility in 100ml water is 22.6g under 90oC.Water solution is acidic, pH (1% solution) is 4.6.Insoluble in ethanol.Monopotassium Phosphate is suitable for general crops and soils, It has many excellent effects, such as significantly increasing production and income, improving quantity, optimizing quality, lodging resistance, disease and insect pests, and preventing premature senility. It also has the effect of overcoming the nutritional deficiency caused by the decline of root aging and absorption ability at the later stage of crop growth. Can not be contacted/mixed with alkaline substances.COAMONOPOTASSIUM PHOSPHATE (MKP) 98% MIN TECH GRADEITEMSPECRESULTCONTENT(KH2PO4)98%MIN.99.53%K2O34.0%MIN34.8%AVAILABLE P2O551.5%MIN52.01%PH VALUE 30g/L4.4-4.84.7INSOLUBLE MATTER IN WATER0.1%MAX.0.004%MOISTURE0.5%MAX0.1%HEAVY METALS,as Pb0.001%MAX0.0004%IRON (Fe)0.003%MAX0.001%ARSENIC, as As0.003%MAX0.0003%CHLORIDES, as Cl0.2%MAX0.001%Monopotassium Phosphate (MKP)Food GradeNO.ItemStandardResult1Maincontent % ≥ 99.099.62K2O % ≥ 34.034.53Moisture % ≤0.20.124PH of 1% solution4.4-4.84.55Phosphorus pentoxide % 51.552.36Water insoluble % ≤ 0.10.027Fluoride, as F % ≤0.0050.00128Arsenic, as As % ≤0.00030.00019Lron (Fe) % ≤0.0030.00110Lead,(As) Pb % ≤0.0010.0002 USEIt is used in industry as buffering agent, culture agent, also as flavoring agent for synthesis of sake by bacterial culture agent, raw material for making potassium metaphosporate, cultivation agent, strengthening agent, leavening agent, fermentation assistant for brewing yeast, and efficient phosphorus and potassium compound fertilizer in agriculture.
