China and India are the leading exporters of sodium fluorosilicate, collectively accounting for over 60% of global export value in recent years, while the United States, Germany, and Mexico represent the largest importers. Sodium fluorosilicate prices have remained relatively stable amid steady demand from water treatment and aluminum production sectors. Export volumes from China have moderated slightly since 2023, while Indian exports have expanded, reflecting a gradual shift in production capacity and trade focus.
Sodium fluorosilicate is a white, crystalline, odorless solid that is non-volatile and sparingly soluble in water. It is an inorganic salt, specifically the sodium salt of fluorosilicic acid. It serves primarily as a raw material for the production of aluminum fluoride and synthetic cryolite in aluminum smelting, and as a source of fluoride in water fluoridation and dental products. It is also used in the manufacture of opalescent glass, ceramics, and as an abrasive in cleaning compounds. Typical application areas include metallurgy, water treatment, glass and ceramic manufacturing, and specialty chemical synthesis.
In enamels for china and porcelain; manufacture of opal glass; as insecticide, rodenticide; mothproofing of woolens. Fluoridating agent for drinking water. Intermediate in production of synthetic cryolite.
It appears as colorless hexagonal crystals. It is odorless and tasteless. It has hygroscopicity. It can be dissolved in a solvent such as ethyl ether but insoluble in alcohol with its solubility in acid is being greater than in the water.
