Caustic soda, also known as sodium hydroxide or industrial alkali, is an inorganic compound with the chemical formula NaOH, which is a strong base. It is a white opaque plume crystal with a melting point of 328 degrees °C. Crisp, soluble in water and emits a lot of heat. Its aqueous solution is alkaline and feels creamy. Caustic soda is easy to deliquescence in the air and can absorb carbon dioxide. But it should be noted that sodium hydroxide is highly corrosive to many substances, such as corrodes fibers, skin, glass, ceramics, etc.
Sodium hydroxide for sale can be divided into solid caustic soda, liquid caustic soda, flake caustic soda, etc. Normally, high purity caustic soda is a colorless transparent crystal. Industrial grade caustic soda contains a small amount of sodium chloride and sodium carbonate, which are white opaque solids in the form of pearls, flakes, blocks, and rods.

The industrial production of sodium hydroxide includes causticization and electrolysis. The causticizing method uses the soda ash aqueous solution and milk of lime to produce caustic soda through causticizing reaction.
The electrolysis method produces sodium hydroxide by electrolysis of saturated saline solution, and by-products chlorine and hydrogen. Therefore, the production of caustic soda by electrolysis is also called the chlor-alkali process.
