Ammonium fluoride is a colorless crystal, easily soluble in water, spreading in moist air. Ammonium fluoride (fluoride) at -27,4 ° C forms a monohydrate, below 0 ° C - solid solutions with ice; when heated by aqueous solutions decomposes with the release of ammonia.
Toxic product.
When burning or heating, toxic fumes are released.
Attacks metal and glass.
In case of contact with skin and mucous membranes, a chemical burn occurs.
With prolonged exposure, it has a destructive effect on the bones and teeth.
We also offer Ammonium Bifluoride.

Yes, these are two names for the same substance with the formula NH₄F. In commercial documents the name “ammonium fluoride” is used. When purchasing, it is important to check not only the name but also the mass fraction of the main substance, impurity content, appearance, packaging, quality certificate and confirmation of compliance with the stated specification. This is especially important if the enterprise has already established purity requirements and permissible impurities.
For ammonium fluoride 97%, the key indicator is the content of the main substance, but along with it, the residue after ignition, sulfates, chlorides, iron, heavy metals and the content of acid ammonium fluoride are checked. These parameters affect batch stability and the predictability of the reagent’s behaviour in the process. During incoming inspection, the integrity of bags, labelling, absence of moisture, caking and foreign inclusions are assessed.
Ammonium fluoride 97% is stored in a dry, ventilated warehouse, in sealed factory packaging and protected from moisture. The product is hygroscopic, so if storage conditions are violated it can cake, become harder to dose and change behaviour when preparing solutions. Bags are placed on pallets, separately from acids, alkalis, oxidisers and materials that could contaminate the batch. For the warehouse, labelling, packaging integrity, batch traceability and restricted personnel access are important.
Ammonium fluoride is classified as a hazardous chemical substance, so working with it requires goggles or a face shield, chemically resistant gloves, protective clothing and protection against inhaling dust. The product must not be allowed to contact the skin, eyes, respiratory tract, or be mixed with incompatible substances outside the process instructions. The workplace must be equipped with ventilation, and decanting and dosing operations are carried out in a way that reduces dusting. In case of a spill, the substance is collected dry into a suitable container and handed over for further processing according to the enterprise’s regulations.
