| Sodium metasilicate is a salt of silicic acid, belonging to inorganic salt products, with the molecular formula Na2SiO3 · nH2O. It is a non-toxic, odorless, and pollution-free white powder or crystalline particle that is easily soluble in water, insoluble in alcohols and acids. The aqueous solution is alkaline and easily hygroscopic and deliquescent when placed in air. It has the ability to remove scale, emulsify, disperse, wet, penetrate, and buffer pH values. It has been listed as one of the "priority fine chemicals for development in China" and "future development priorities for inorganic chemical products in China" by the state | |||||||||
