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.
4.Specifications:(Technical standard:GB/T1918-1998)
