Sodium Fluoride
A white crystalline powder or colourless crystals, sparingly soluble in water with a slightly alkaline reaction. Widely used as a fluorinating agent, fluxing agent, preservative and water fluoridation agent.
ANFA's industrial sodium fluoride is produced to GB/T 4293, graded by assay and impurity profile for aluminium electrolysis, abrasives, welding consumables and wood preservation. Dental and pharmaceutical grades with tighter heavy metal and arsenic limits are available.
International trade names: Fluoruro de sodio (Spanish), Fluoreto de sódio (Portuguese), Фторид натрия (Russian). Overseas buyers frequently search for this product under these local-language names.

Hydrofluoric Acid
An aqueous solution of hydrogen fluoride (HF). A colourless, fuming and highly corrosive liquid that attacks glass and siliceous materials. ANFA supplies the full 30–70% concentration range across industrial and electronic (UP / EL) grades, tailored to your process.
Learn moreAmmonium Bifluoride
White needle-like crystals, deliquescent and prone to caking; soluble in water, slightly soluble in alcohol. The aqueous solution is acidic and attacks glass. Decomposes into ammonia and hydrogen fluoride on heating.
