Granular caustic soda is solid sodium hydroxide, which has all the chemical properties of sodium hydroxide. When placed in the air, it will absorb moisture in the air, deliquescence, and react with carbon dioxide to deteriorate. The packaging requires a dry, sealed package.
Granular caustic soda is also called pearl caustic, a kind of solid caustic soda (sodium hydroxide) product, chemical formula: NaOH. According to the particle size, it can be divided into coarse-grained alkali and particulate alkali. Granulated caustic soda is more usable than flake caustic soda, but the production process of granulated caustic soda is more difficult and more complicated than flake caustic soda. Therefore, the price of granulated caustic soda is naturally higher than that of flake caustic.

| Conclusion | Qualified | |
Among the solid caustic sodas, flake caustic soda and granular caustic soda are the most common and used solid caustics, and granular caustic soda is more useful than flake caustic soda, but the production process of granular caustic soda is more difficult and more complicated than flake caustic soda. Therefore, the price of granular soda is naturally higher than that of flake soda.
Granular caustic soda is mainly used as a chemical raw material and an important chemical basic raw material with a wide range of uses. In the chemical industry, it is used in the manufacture of formic acid, oxalic acid, borax, phenol, sodium cyanide, soap, synthetic fatty acid, synthetic detergent, etc. In the textile printing and dyeing industry, it is used as a solvent for cotton cloth desizing agent, scouring agent, mercerizing agent, vat dye and Haichang blue dye. Used in the smelting industry to manufacture aluminum hydroxide, aluminum oxide and metal surface treatment agents. In the instrument industry, it is used as an acid neutralizer, decolorizer, and deodorizer. The adhesive industry is used as starch gelatinizer and neutralizer. In addition, it is widely used in enamel, medicine, cosmetics, tanning, coatings, pesticides, glass and other industries.
