Basic Information

Ammonium chloride
chloramine
halogen sand
white crystalline salt

Ammonium chloride is a white crystalline salt that dissolves in water and forms mildly acidic solutions. Humid conditions can encourage moisture uptake and caking, while heating produces reversible dissociation. Its industrial uses span battery manufacture, leather tanning, electroplating and adhesive formulations. It is also employed as an acidic nitrogen fertilizer for grain and fiber crops.

product description

High Solubility‌:Soluble in water, ethanol, and liquid ammonia.


‌Controlled Acidity:Aqueous solution is weakly acidic, acidity increases with heating.

‌

Controlled Volatility‌:Volatilizes at 100°C, dissociates at 337.8°C, and recombines under cold exposure.

‌

Moisture Absorption Adaptability‌:Low moisture absorption but can absorb moisture in humid weather to prevent dusting.


Products Description of Ammonium chloride CAS#12125-02-9

Ammonium chloride ("chloramine"/"halogen sand") is a weakly acidic white crystalline salt soluble in water, ethanol and liquid ammonia. It volatilizes at 100 °C, dissociates at 337.8 °C, sublimes at 350 °C and boils at 520 °C. Low-hygroscopic but caking-prone in humidity, it corrodes most metals (especially copper) but not pig iron. Produced by ammonia-HCl neutralization, it decomposes reversibly only in open systems.


Product Applications of Ammonium chloride CAS#12125-02-9

Ammonium chloride is used in batteries, tanning, electroplating, pharmaceuticals and adhesives, and as a 24%–25% nitrogen acidic fertilizer for grains and fiber crops.
Specifications (GB-2946-82): ≥99.3% dry purity, ≤1.0% moisture, pH 4.2–5.8, with strict impurity limits.
