Sodium Fluorosilicate, identified by CAS number 16893-85-9 and the chemical formula Na2SiF6, is an inorganic compound with distinct chemical and physical properties that dictate its wide range of industrial applications. Understanding this profile is essential for any professional involved in its procurement or use.

Chemically, it is the sodium salt of fluorosilicic acid. It typically appears as a white crystalline powder. Its physical characteristics include an odorless and tasteless nature, with a density of approximately 2.68 g/mL at 25°C. While it is insoluble in alcohol, its solubility in water increases with temperature, a property that is leveraged in various aqueous-based applications. The compound decomposes when heated strongly, releasing toxic fumes.

From a reactivity standpoint, Sodium Fluorosilicate solutions can be sensitive to hydrolysis in alkaline environments. When exposed to acids, it can release silicon tetrafluoride. Safety data highlights its toxicity, particularly if ingested or inhaled, necessitating careful handling and appropriate personal protective equipment (PPE). This includes dust respirators, protective gloves, and eye protection to prevent exposure.

Manufacturers and suppliers of Sodium Fluorosilicate emphasize its stability under normal storage conditions. However, it is important to store it separately from incompatible materials such as strong acids and oxidizing agents, and to keep it in a dry environment to maintain its integrity. Adherence to safety protocols outlined in Material Safety Data Sheets (MSDS) is critical for safe handling, storage, and transportation.

The purity of Sodium Fluorosilicate is a key specification for buyers. Industrial grades typically offer a purity of 99% or higher, which is vital for applications in water treatment, glass manufacturing, and agrochemicals, where precise chemical compositions are required. Procurement managers often request detailed specifications and CoAs from their suppliers to ensure the material meets their exact needs.
