Uses of Ammonium Sulphate [(NH₄)₂SO₄] in Various Industries
Ammonium sulphate is a versatile chemical compound widely used across agriculture, chemical processing, pharmaceuticals, textiles, and more. Below is a comprehensive industry-wise application list:
🌾 1. Agriculture & Fertilizer Industry
Primary Use: As a nitrogen-based fertilizer (contains ~21% nitrogen and 24% sulfur)
Purpose:
Promotes leafy plant growth and chlorophyll production
Provides sulphur, critical for protein synthesis in crops
Preferred For: Rice, wheat, tea, sugarcane, cotton, pulses
🧪 2. Chemical Industry
Used As:
Intermediate for manufacturing other ammonium salts
Acidifier in pH control
Catalyst carrier in specialty chemical production
Role: Helps in maintaining ionic balance in chemical processes
🧫 3. Pharmaceutical & Biotech Industry
Key Role: In protein purification and precipitation techniques (salting out)
Applications:
Stabilizing enzymes and proteins during formulation
Used in vaccine development and biotechnology labs
🧼 4. Detergent & Cleaning Products
Function:
pH buffer and filler in laundry detergents
Used in fabric softeners to stabilize product viscosity
👚 5. Textile & Dyeing Industry
Purpose:
Acts as a mordant in dyeing processes (fixes dyes on fabrics)
Helps in pH regulation during bleaching and scouring
Benefit: Reduces dye loss, improves color intensity
🧱 6. Construction & Cement Industry
Usage:
As a setting accelerator in concrete mixtures
Minimizes corrosion of steel reinforcements in concrete
Secondary Role: Enhances fire resistance in construction boards
🛢️ 7. Petroleum Industry
Application: As an additive in drilling muds to reduce water loss
Benefit: Controls clay swelling and improves mud stability
🧯 8. Fire Retardant Industry
Used In: Manufacturing fire-retardant coatings and powders
Function: Releases ammonia and water vapor to cool fires and reduce oxygen availability
🧃 9. Food Processing Industry (Limited/Regulated Use)
E-number: E517 – approved in some countries
Use: As a yeast nutrient in bread-making and fermentation processes
Note: Limited to technical food processing, not for direct consumption
🚜 10. Animal Feed Industry
Usage: As a nitrogen source in ruminant feeds (under strict regulation)
Caution: Overuse can cause toxicity — monitored by veterinary guidelines
