Potassium nitrate Chemical Properties,Usage,Production

Chemical Properties White solid General Description A white to dirty gray crystalline solid. Water soluble. Noncombustible, but accelerates the burning of combustible materials. If large quantities are involved in fire or the combustible material is finely divided an explosion may result. May explode under prolonged exposure to heat or fire. Toxic oxides of nitrogen are produced in fires. Used in solid propellants, explosives, fertilizers. Air & Water Reactions Soluble in water. Reactivity Profile Potassium nitrate mixed with alkyl esters may explode, owing to the formation of alkyl nitrates; mixtures with phosphorus, tin (II) chloride, or other reducing agents may react explosively [Bretherick 1979. p. 108-109]. Powdered antimony mixed with Potassium nitrate explodes when heated [Mellor 9:282 1946-47]. A mixture of antimony trisulfide and Potassium nitrate explodes at a red heat [Mellor 9:524. 1946-47]. Arsenic disulfide forms explosive mixtures when mixed with Potassium nitrate, [Mellor 9:270.1946-47]. A mixture of sodium acetate and Potassium nitrate may cause an explosion [Pieters 1957. p. 30]. A mixture of Potassium nitrate and sodium hypophosphite constitutes a powerful explosive [Mellor 8:881. 1946-47]. A mixture of powdered zirconium and Potassium nitrate explodes when heated above the melting point [Mellor 7:116. 1946-47]. Health Hazard Exposure can cause mild irritation of eyes, nose and throat.
