Properties: Colorless cubic crystals or white crystalline powder. Salty, cool taste with slight bitterness. Relative density 1.527. Sublimes at 350°C. Boiling point 520°C. Highly soluble in water, soluble in liquid ammonia, slightly soluble in alcohol, insoluble in acetone and ether. Begins significant volatilization at 100°C, dissociates into ammonia and hydrogen chloride at 337.8°C, recombines into extremely fine ammonium chloride particles upon cooling, forming a dense white mist that does not settle easily and is very difficult to redissolve in water. Low hygroscopicity, but may absorb moisture and form lumps in damp or rainy weather. Aqueous solution is weakly acidic, acidity increases with heating. Corrosive to ferrous and other metals, particularly corrosive to copper, non-corrosive to cast iron.
Packaging: Outer woven bag, inner plastic bag, net weight 25/50 KG.
Protection: Highly corrosive, avoid skin contact. Permissible concentration of ammonium chloride fumes in air is 10 g/m3. Operators should wear work clothes, masks, latex gloves, etc. Equipment must be sealed, and workshop ventilation should be adequate.
Storage and Transportation: Store in a cool, ventilated, dry warehouse, protect against moisture. Avoid co-storage and mixed transport with acids and alkalis. Protect from rain and direct sunlight during transportation. Handle with care during loading and unloading to prevent packaging damage. In case of fire, extinguish with water, sand, or carbon dioxide fire extinguishers.
Uses: Primarily used in ore dressing and tanning, agricultural fertilizer. Used as a dyeing auxiliary, electroplating bath additive, metal welding flux. Also used in tin and zinc plating, pharmaceuticals, candle making, adhesives, chromizing, precision casting, and manufacturing dry cells and batteries, as well as other ammonium salts.

Specification: Potassium-containing Agricultural Grade
