High Purity and Stable Crystal Form：Appears as white crystals or colorless hexagonal crystals with uniform structure, ensuring consistent quality and easy handling in industrial applications.
Good Chemical Reactivity：Easily decomposes in alkaline solutions and at high temperatures to form useful products such as sodium fluoride and silica, making it suitable as a reactive intermediate in chemical processing.
Excellent Moisture Absorption Ability：Possesses hygroscopic properties that enhance its performance in formulations requiring controlled moisture interaction.
Water Solubility：Sodium fluorosilicate is only slightly soluble in water, with solubility varying according to temperature.
Product Description of Sodium Fluorosilicate CAS#16893-85-9
Sodium fluorosilicate is available as white crystals, crystalline powder or colorless hexagonal crystals. It is odorless, tasteless and hygroscopic, with a relative density of 2.68. It is soluble in ethyl ether, insoluble in alcohol, and more soluble in acids than in water. It decomposes in alkaline solution into sodium fluoride and silica, and breaks down into sodium fluoride and silicon tetrafluoride when heated to around 300 °C.
Product Application of Sodium Fluorosilicate CAS#16893-85-9
Sodium hexafluorosilicate is used for water fluoridation and as a raw material for opal glass and ore refining. It serves as feedstock for manufacturing fluoride chemicals including sodium fluoride, sodium hexafluoroaluminate, potassium hexafluorosilicate, ammonium fluoride and calcium fluoride. It is also applied as a flotation agent, wet etching component, wood preservative, brazing flux and welding compound, as well as an active ingredient in concrete.
