Molecular Formula: KNO₃
Molecular weight:101.11
Physicochemical Properties: KNO3 is the rhombic system crystal powder or grain. Specific Density: 2.1109, Melting Point :333℃. While heated up to as high as 400℃, 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(0℃，13.3g/100gH2O;30℃，45.8g/100H2O;100℃，246.0g/100gH2O),soluble in liquid ammonia and glycerin, insoluble in alcohol.
Applications and Usages:: KNO3 is used raw material to make black powder, front line , blaze and some other things. In pottery and porcelain industry it can 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 be used as mill run medicament. Edible KNO3 can be used as chromogen and preservatives in meat food.
Packaging: 50kg/bag, plastic inside and knitting bag outside with "oxidant"printed on. Food grade KNO3 is packaged in plastic bags which is used for food only. The sign of "food additives"can be seen on the bag.
