Description:

Caustic soda flakes are the solid, flaked form of sodium hydroxide. They are produced through the evaporation of liquid caustic soda, resulting in thin, white flakes with high purity (usually ≥98% NaOH). Caustic soda is a strong alkali, highly corrosive, and reacts readily with water, acids, and various organic substances.

Key Properties:

• Strong alkali used in various chemical processes

• Hygroscopic: Absorbs moisture and CO₂ from the air

• Highly corrosive to metals, skin, and eyes

• Generates heat when dissolved in water (exothermic reaction)

Applications:

• Chemical manufacturing (e.g., sodium compounds, detergents)

• Textile processing (mercerization of cotton)

• Pulp and paper industry (kraft process)

• Water treatment (pH adjustment, softening)

• Soap and detergent production

• Petroleum refining

• Aluminum and metal processing
