Formula:KNO3
Formula Weight:101.10
Properties and Applications:
Potassium Nitrate is colorless crystal, white powder or prilled form.It is easily soluble in water, and the liquid ammonia but in anhydrous alcohol. It can not deliquest in the air. As strong oxidizer,it will burn and explode when mixied with organics. It 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 both of heat treatment, cigarette paper, concentrating agent; as chromogen agent,preserving agent in food industry
