Global Fluorosilicic Acid Market
The fluorosilicic acid market size was valued at USD 467.46 million in 2024. The market is projected to grow from USD 497.33 million in 2025 to USD 925.95 million by 2034, exhibiting a CAGR of 7.2% during 2025–2034.
Market Overview
Fluorosilicic acid (H₂SiF₆), a byproduct of phosphate fertilizer production, is a clear, fuming liquid primarily used in the fluoridation of drinking water and in various industrial processes. Its role in public health through water fluoridation, combined with its utility in metal treatment and textile processing, has made it a critical commodity in both developed and developing economies.
Beyond water treatment, fluorosilicic acid is used in the production of aluminum, as a wood preservative, in the glass industry, and as a pH adjuster. The growing emphasis on clean water initiatives, rapid urbanization, and industrial development are major forces propelling the market forward.
Market Segmentation
By Grade:
25% Concentration: Most commonly used for public water fluoridation due to its balanced fluoride content.
35% Concentration: Found in chemical processes requiring slightly higher fluoride strength.
40% Concentration: Used in specialized applications such as heavy-duty metal treatment and industrial cleaning.
By Application:
Water Fluoridation: Remains the largest and most critical application, accounting for nearly 45% of the market share.
Textile Processing: Used in fiber conditioning and cleaning processes to improve fabric quality.
