FAQ - Technical & Supply Chain
-
Q:
Are Ammonium Bifluoride and Ammonium Hydrogen Difluoride the same salt?
A: Yes. Both names identify NH4HF2, CAS 1341-49-7. It is not ammonium fluoride, ammonium fluoroborate or a prepared etching solution. State the CAS number, solid assay and intended industrial process when requesting a grade. -
Q:
What is Ammonium Bifluoride used for?
A: It is used in controlled fluoride-containing industrial processes such as metal surface treatment, glass etching and cleaning, aluminum processing and selected chemical syntheses. Process and material compatibility must be reviewed before use because the material is corrosive and releases hazardous fluoride species. -
Q:
Which specifications should be agreed for industrial Ammonium Bifluoride?
A: Confirm assay and method, moisture, water-insoluble matter, ammonium fluoride or free-acid basis where specified, chloride, sulfate, hexafluorosilicate and relevant metals. Etching and metal-treatment processes may need different impurity limits. -
Q:
What should be confirmed before Ammonium Bifluoride shipment?
A: Agree net weight, moisture-resistant compatible packaging, pallet protection, labeling and destination transport requirements. Ammonium Bifluoride is commonly shipped as UN 1727, Hazard Class 8 corrosive solid; confirm the exact packing group, local handling, ventilation and waste controls before shipment. -
Q:
What are typical physical properties of Ammonium Bifluoride?
A: Ammonium Bifluoride is normally a white crystalline, flake or granular solid that is hygroscopic and readily water-soluble. Typical values are density about 1.5 g/cm3, melting around 125-126 C, and boiling or decomposition around 230-240 C.
