Calcium Fluoride (Fluorspar)
The originating raw material of the fluorine chemical industry. ANFA supplies acid-grade fluorspar concentrate (CaF₂ 85–97%) and metallurgical grade fluorspar for HF production, metallurgical fluxing and construction materials.
Through stable mining and beneficiation channels, we run batch inspection and particle-size control on fluorspar to keep CaF₂ assay, silica and sulphur/phosphorus within downstream HF production limits. Acid-grade material is available as powder, lump or briquette with agreed moisture levels, plus blending advice to optimise your production cost.
International trade names: Fluoruro de calcio (Spanish), Fluoreto de cálcio (Portuguese), Фторид кальция (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.
Learn moreSodium 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.
