High purity potassium nitrate

1.Name:Potassium nitrate

　　Formular: KNO₃

　　Molecular weight:101.1

2.Property:
　　KNO₃ is the rhombic system crystal powder or grain. Density:2.019,Melting Point:334℃.While being heated up to about
　　400℃,it will decompose and release oxygen and turn into potassium nitrite,as the heating going on, it will eventually
　　decompose into potassuum oxide and nitrogen oxide. Dissolved in water,soluble in liquid ammonia and
　　glycerin,insoluble in absolute ethyl alcohol and ether. It is not liable to deliquesce and is oxidant.

3.Usage:
　　KNO₃ is used in industry of fine chemicls,conducting heat molten salt of organic chemical industry( melamine,phthalic

　　anhydride,acroleic acid,cis-butenedioic anhydride,pyrocatechin etc.) ,metal heat treatment,special glass,blasting
　　fuse,blaze,medicine,making ceramic glaze,cigarette paper,black gunpowder,match,candlewick,colour TV picture
　　tube,chemical reagent,catalysator and milling of ares.Potassium Nitrate usde for agriculture can be used as compound
　　fertilizer and foliar spray fertilizer for economic crop such as flower,vegetable and fruiter. In addition, it can be used as
　　adjuvant material in metallurgy and food industry.
