Ammonium Chloride

Ammonium chloride, commonly known as sal ammoniac, is an inorganic compound with the chemical formula NHaCl. It is a typical inorganic ammonium salt composed of ammonium ions (NH) and chloride ions (Cl). As a fundamental raw material, it is widely used in industries such as agriculture, chemicals, pharmaceuticals, electroplating, and dry battery manufacturing due to its high cost-performance ratio and stability.

1. Industrial Field - Metal Welding and Smelting
This is the most classic use of ammonium chloride. It is used as a flux during welding to remove oxide films (such as rust) from metal surfaces, helping the solder adhere better. In addition, it is also used in the production of tin plating, galvanizing, and dry cells (as a component of the electrolyte).

2. Agricultural Field -Nitrogen Fertilizer
Ammonium chloride is a physiologically acidic, quick-acting nitrogen fertilizer with a nitrogen content of about 24%-25%. It is suitable for crops such as rice, wheat, cotton, and hemp.

3. Pharmaceutical Field - Expectorant
When taken orally as a low-concentration solution, ammonium chloride stimulates the gastric mucosa, causing mild nausea. This reflexively promotes the secretion of thin fluids from the respiratory tract, thinning mucus and making it easier to cough up. It is commonly used to treat coughs with phlegm caused by colds, bronchitis, and similar conditions.
