Sodium fluorosilicate

Product Name: Sodium Fluorosilicate

Chemical Formula: Na₂SiF₆

Key Features: White crystalline powder or granular solid, slightly soluble in water, insoluble in alcohol, exhibits weak acidity in aqueous solution

Main Applications by Industry:

Water Treatment: Used as a fluoridating agent for municipal drinking water supplies to prevent tooth decay; also acts as a coagulant aid in certain wastewater treatment processes.

Glass & Ceramics: As an opacifier in enamel and ceramic frits; used in the production of specialty glasses and for surface etching or frosting of glass products.

Construction & Cement: Added to cement and concrete mixtures as a setting accelerator and hardening agent; improves water resistance and strength of concrete.

Textile Industry: Used as a mothproofing agent and for acid-resistant treatment of textile fibers.

Wood Preservation: Functions as a wood preservative to protect against fungal decay and insect attack, often used in combination with other preservatives.

Surface Treatment & Metal Finishing: Used in metal surface passivation, as a corrosion inhibitor, and in the preparation of certain plating baths.

Pesticides & Agriculture: As an active ingredient in some rodenticides and insecticides; also used as a soil treatment agent.

Chemical Synthesis: Serves as a raw material for producing other fluoride salts, hydrofluoric acid, and cryolite (Na₃AlF₆) used in aluminum smelting.

Electroplating & Batteries: As an additive in electroplating baths and as a component in some battery electrolytes.

Handling & Safety:
Toxic if swallowed. Causes severe skin and eye irritation. May cause respiratory irritation if dust is inhaled. Use with adequate ventilation. Wear protective gloves, goggles, and dust mask. Wash thoroughly after handling. Keep away from food and drinking water.
