Fluorosilicic Acid (FSA)

Description

1. Product Overview

Fluorosilicic Acid (FSA), also known as Hexafluorosilicic Acid (H₂SiF₆), is a clear, corrosive inorganic acid primarily generated as a by-product of phosphate fertilizer production. It is widely utilized in water fluoridation, aluminum fluoride manufacturing, metal surface treatment, and specialty chemical synthesis.

FSA offers a highly cost-efficient and concentrated fluorine source, delivering reliable performance across municipal and industrial applications. As global demand grows for water treatment chemicals and fluoride-based intermediates, Fluorosilicic Acid remains strategically important due to its scalable availability, competitive pricing, and integral role in downstream chemical value chains.
