Industry Wise Application
Food Additives
- Table Salt & Seasonings:Used to prevent caking and clumping in food-grade sodium chloride.
- Flow Improvement:It acts as a coating agent, decreasing the solubility of salt in moisture, thus preventing crystallization/re-clumping.
- Regulatory Standard:Approved for use in salts at low levels (typically E535).
Industrial Applications
- Pigment Production:Key raw material in manufacturing Prussian Blue (iron blue/ferric ferrocyanide), used in paints, inks, and coatings.
- Metallurgy & Surface Treatment:Used in the case-hardening and carburization of carbon steel, and in pickling baths to treat metal surfaces.
- Mining & Ore Flotation:Acts as a separation agent in mining, particularly for separating copper from molybdenum ores.
- Photography:Utilized for toning, bleaching, and fixing in photographic processes.
- Petroleum Refining:Employed in the removal of mercaptans.
Chemical Manufacturing
- Pulping Process:Used in the sulfite process to separate lignin from cellulose fibers.
- De-inking:Used in the recycling process to remove ink from paper.
Water Treatment
- pH Control:Used in swimming pools and water treatment plants to raise pH levels and neutralize acidic water.
- Corrosion Protection:Prevents corrosion of water pipes by maintaining alkaline conditions.
Food & Personal Care
- Food Additive (E500):Acts as an acidity regulator, stabilizer, and raising agent. It is notably used in the production of Japanese ramen noodles (kansui) to give them a chewy texture.
- Toothpaste Formulation:Used as a foaming agent and abrasive in some toothpaste brands.
Textile & Dyeing
- Dye Fixative:Acts as a mordant in reactive dyeing to ensure proper chemical bonding of dyes with cellulose (plant) fibers.
- Scouring Agent:Used to remove impurities, natural oils, and waxes from raw fabrics.
Other Application
- Brick Industry:Utilized as a wetting agent to reduce the amount of water needed for extruding clay.
- Metallurgy:Used in the froth flotation process to maintain a favourable pH.
- Photography:Used as a pH regulator in film developing agents.
