Sodium Hydroxide widely known as Caustic Soda, is an essential inorganic alkali used in countless manufacturing processes. Its ability to react with acidic substances, emulsify fats, and adjust pH levels makes it central to industrial chemistry. Caustic Soda is produced primarily through electrolysis of sodium chloride brine and is available as flakes, pellets, pearls, and liquid.
Material Properties
NaOH is a highly hygroscopic material, quickly absorbing moisture and CO₂ from the air. It forms a slippery, soapy texture when reacting with water or fats. Its aqueous solutions are strongly alkaline, with a pH value approaching 14. Sodium Hydroxide reacts vigorously with acids to form salts and water.
Key Functions Across Industries
Water Treatment
NaOH regulates pH of municipal water systems and prevents pipe corrosion.
Soap & Detergent Manufacturing
Sodium Hydroxide enables saponification of fats, producing soap and glycerin.
Aluminum Processing
It dissolves bauxite ores in the Bayer process to produce alumina for aluminum manufacturing.
Pharmaceutical & Cosmetic Sector
Used as pH regulator and neutralizing agent, and in controlled functional roles in formulations.
Construction & Building Materials
Used in additive manufacturing of concrete admixtures and sealing compounds.
Battery & Energy Storage
In alkaline batteries, NaOH acts as electrolyte and conductivity enhancer.
