Sodium Carbonate (Soda Ash)

1. Glass Industry

• Primary use: Major raw material in glass manufacturing.

• Helps lower the melting point of silica, making glass production more efficient.

• Used in soda-lime glass, flat glass, container glass, and specialty glass.

2. Detergents and Soap Industry

• Acts as a water softener by binding calcium and magnesium ions.

• Used in laundry detergents and dishwashing powders to improve cleaning efficiency.

• Helps in soap production by saponifying fats.

3. Chemical Manufacturing

• Used to produce sodium bicarbonate (baking soda), sodium silicate, sodium phosphates, and other sodium compounds.

• Acts as a pH regulator in chemical processes.

4. Water Treatment

• Adjusts water hardness and pH levels in municipal and industrial water treatment.

• Helps prevent pipe corrosion and scaling.

5. Pulp and Paper Industry

• Used in pulping wood and paper bleaching.

• Helps remove lignin from wood fibers in chemical pulping.

6. Food Industry

• Food-grade soda ash is used as:

  • Raising agent in baked goods.

  • pH regulator in processing certain foods like olives and noodles.

7. Textile Industry

• Used in dyeing and bleaching textiles.

• Helps fix dyes to fabrics.

• Acts as a pH regulator in textile processing.

8. Metallurgical Processes

• Used in metal extraction (like aluminum and copper) and metal cleaning.

• Helps remove impurities from ores.

9. Miscellaneous Uses

• Glass etching.

• Making artificial gemstones.
