Description

Potassium nitrate

Molecular Formula: KNO3
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 mainly applied in TV glass, glass refining agent and motor light glass；compound fertilizer and foliar spray fertilizer；fireworks and black powder；drugs and catalyzer；ceramic and enamel；salt bath of heat treatment, cigarette pater, concentrating agent；conservatives and chromogen in Food industry, etc.
