Physical and chemical properties	KN03 molecular weight 101.11 white transparent orthorhombic crystal or rhombic crystal or white powder. No smell, non-toxic, salty and spicy with cool feeling. Density 2.11g/cm3. Melting point 334 ℃. No deliquescence in Air. Soluble in water, liquid ammonia and glycerin, insoluble in absolute ethanol and ether. Decompose and release oxygen at 334 ℃, liberate oxygen at 400 ℃, generate sub-Potassium nitrate, and continue heating to generate oxidation Potassium. It is a strong oxidant. Contact with flammable materials and organic matter can cause combustion and explosion, and toxic and irritating gases can occur. When heated with carbon or sulfur, it can emit strong light and burn. Application Field The pharmaceutical industry is mainly used to produce penicillin Potassium salt, rifampicin and diuretic, sweating and cooling. The food industry is used to match meat and acts as a preservative in luncheon meat. The machinery industry is used for heat treatment (metal quenching) as a salt bath for quenching. The glass industry is used in the production of glassware, plays the role of temperature-resistant hardening glass, and is also used as a glass clarifying agent. It is used as a compound fertilizer for crops and flowers in agriculture.
