Industrial Ammonium Hydrogenfluoride
[Molecular Formula] NH4HF2
[Properties]
Ammonium bifluoride is white needle-like crystal, easy deliquescence and agglomeration, soluble in water and slight soluble in alcohol; decompose to ammonia and ammonium bifluoride in heat water, decompose to ammonia and hydrogen fluoride when being heated, its aqueous solution is acidic and can corrode glass.

Ammonium Bifluoride Features

Solubility: Ammonium bifluoride is highly soluble in water, meaning it readily dissolves in water to form an aqueous solution. This solubility makes it useful for various applications where a water-soluble fluoride source is required.

Corrosive Nature: Ammonium bifluoride is corrosive to many materials, including metals, glass, and ceramics. It reacts with these materials, releasing hydrofluoric acid, which is highly corrosive and can cause severe burns.

Acidic Nature: Ammonium bifluoride is an acidic compound. When dissolved in water, it releases hydrogen ions (H+), resulting in an acidic solution. The pH of a solution containing ammonium bifluoride is typically below 7.

3. Product Applications

Metal Surface Treatment: Ammonium bifluoride is used as an etchant and surface treatment agent for metals, particularly aluminum and stainless steel. It effectively removes oxides, scales, and other impurities from the metal surfaces, preparing them for further processing, such as painting, coating, or bonding.

Glass Etching and Frosting: The corrosive nature of ammonium bifluoride makes it useful for glass etching and frosting. It is applied to glass surfaces to create decorative patterns, logos, or frosted designs by selectively removing the glass material.

Cleaning Agent: Ammonium bifluoride is employed as a cleaning agent for various purposes. It helps remove mineral deposits, such as limescale or rust stains, from surfaces like tiles, ceramics, and bathroom fixtures. It is also used for cleaning industrial equipment, especially those exposed to harsh environments.
