Description

Fluorosilicate CAS NO 17084-08-1 is an inorganic salt primarily known for its role as a source of fluoride ions and silicon. This compound is valued in industrial processes for its reactivity and utility in surface treatment and chemical synthesis. It serves as a critical raw material for manufacturers in the ceramics, metal surface finishing, and water treatment industries seeking consistent quality and reliable supply.

Application

• Metal Surface Treatment: Used in aluminum anodizing and metal brightening baths to produce hard, corrosion-resistant finishes.
• Ceramics and Glass Manufacturing: Acts as a fluxing agent and opacifier to modify melting points and enhance product durability.
• Water Fluoridation and Treatment: Employed as a source of fluoride for municipal water systems and in industrial water conditioning to control scale and corrosion.
• Chemical Synthesis: Serves as a precursor or intermediate in the production of other silicon and fluorine-based chemicals.
• Wood Preservation: Utilized in formulations to impart fire-retardant and decay-resistant properties to timber.
• Laundry and Cleaning Products: Incorporated in certain industrial and institutional cleaning formulations for stain removal and whitening.
