Product name: Potassium Nitrate 99.4% 
Potassium nitrate formula: KNO3
CAS No.:  7757-79-1
EINECS No.: 231-818-8
Appearance: Colorless transparent prismatic or white particles or crystalline powder. Spicy and salty cool feeling. Micro-deliquescence, deliquescence slightly smaller than sodium nitrate.
Solubility: soluble in water, insoluble in ethanol, ether. Dissolved in water, heat, the solution temperature decreases. 
Chemical properties: potassium nitrate can participate in redox reaction, 
S +2KNO3+3C ==== K2S +N2↑ +3CO2↑ 
during this reaction, sulfur KNO3 is as the oxidant, this is the black powder reaction. 
Nitrate de potassium is oxidizing in an acidic environment; Heating decomposition will generate oxygen; it can cause burning and explosion if touch or impact the organic matter, phosphorus, sulfur.
The application is to make black gunpowder, such as mine gunpowder, fuse. Firecrackers etc. Also used in fireworks to produce purple sparks. Industrial grade potassium nitrate also used in tempered glass production.

At present JubaoChem can offer 99.3%-99.9% purity potassium nitrate with powder type, crystal type. Usually customer buy 99.3-99.7% for fertilize, the fireworks production usually use the purity of 99.4%, 99.9% purity is for tempered glass production.
