AMMONIUM CHLORIDE
Technical grade
Ammonium chloride is an inorganic compound with the chemical formula NH₄Cl. It is a white crystalline salt that is highly soluble in water, forming a slightly acidic solution. Ammonium chloride occurs naturally in volcanic areas but is primarily produced synthetically. It is a highly versatile compound with applications in agriculture, metalworking, pharmaceuticals and more. Its ability to provide nitrogen, clean surfaces, and regulate acidity makes it indispensable in many industries.

Common Uses of Ammonium Chloride
1. Fertilizer
- Role: A source of nitrogen for plants.
- Application: Commonly used as a nitrogen fertilizer, especially in rice cultivation. It provides ammonium ions that plants can readily absorb.
2. Metalworking and Industrial Processes
- Flux in Metalwork: Used as a flux in soldering, brazing, and galvanizing to clean and prepare metal surfaces by removing oxides.
- Batteries: Historically used as an electrolyte in dry cell batteries (e.g., zinc-carbon batteries).
3. Laboratory
- Used in cooling baths to produce low temperatures.
- Used as a buffer solution when used in conjunction with ammonia.
4. Industry
- Used in fireworks.
- Used in hair shampoos and cleaning products.
- Used in plywood glue.
5. Textile and Dyeing Industry
- Dye Fixation: Helps fix dyes in the textile industry, ensuring better adherence of the dye to the fabric.
- Used to add lustre to cotton.
6. Agriculture
- Soil pH Adjustment: Used to acidify alkaline soils.
7. Water Treatment
- Ammonia Source: Provides ammonia in water treatment processes to form chloramines for disinfection.
8. Fireproofing
- Flame Retardant: Applied to textiles, wood, and paper products to improve their fire resistance.
