Potassium Nitrate features:1) Potassium nitrate 2) Molecular formula: KNO3 3) Molecular Weight: 101.114) Physicochemical properties: KNO3 is the rhombic system crystal powder orgrain5) Specific density: 2.11096) Melting point: 333°C. While heated up to as high as 400°C, it will decompose and release oxygen and turn into nitrite potassium, then with the heating going on, it will eventually decompose into potassium oxide and nitrogen oxide. Dissolved in water (20°C, 13.3g/100g H2O; 30°C, 45.8g/100H2O; 100°C, 246.0g/100gH2O); soluble in liquid ammonia and glycerin, insoluble in alcohol7) Applications and usages: KNO3 is used raw material to make black powder, front line, blaze for military and some other things. In pottery and porcelain industry itcan be used in making color ceramic glaze; it also can be used in making glass clarifier, the auto dynamo glass ,optical glass and kinescope glass. Also it is used in making medicine such as penicillin sylvine and rifampicin. It can beused as mill run medicament. Edible KNO3 can be used as chromogen and preservatives in meat food8) Item unit optical G. Ind.G. Agri.G. Ceramic G. crystal.
