Ammonium fluoride, is an inorganic compound, chemical formula NH4F, is an ionic compound, white crystalline powder, easy to deliquescence, soluble in water, methanol, slightly soluble in ethanol, insoluble in , mainly used as glass etching agent, wood and winemaking preservative, disinfectant, analytical reagent, zirconium drip reagent and fiber mordant and extraction of rare elements reagent.
Ammonium fluoride is used for etching and frosting of glass, preservation of food and in woods, in printing textile, and as mothproofing agent. It is used in chemical analysis and as an antiseptic in brewing beer. It has also been used in commercial uses like, building materials, printing and dying textiles and in semiconductors. It has also been used in site-limited use as a surface treatment (for metal and non-metal surfaces), and as an intermediate in manufacturing.

It is a white crystal with corrosive to skin and toxic. It is soluble in water and methanol, slightly soluble in ethanol, insoluble in propanone and liquid ammonia. When it is in hot water decomposition will occur to release ammonia and ammonium bifluoride. It is white or colorless transparent orthorhombic crystal at room temperature, with a slightly sour taste. It is easily deliquescent when heated or in hot water and decomposes into ammonia and hydrogen fluoride. Decomposed in hot water, the aqueous solution is strongly acidic. It is obtained by neutralizing anhydrous hydrofluoric acid with liquid ammonia. Mainly used as glass etching agent, wood and wine preservative, disinfectant, zirconium drops reagent and fiber mordant and reagents to extract rare elements. Chemical reagents, glass etchants (used in conjunction with hydrofluoric acid), disinfectants and preservatives in the fermentation industry, solvents for beryllium oxide to beryllium, surface treatment agents for silicon steel sheets, and production of ceramics, magnesium alloys, aluminum alloys, etc., boilers Scale removal and elution of feedwater systems and steam generation systems, acid treatment of oilfield sands, catalysts for alkylation and alkylation of isomerized components.
Ammonium Fluoride(CAS:12125-01-8)
Ammonium hydrogen fluoride is mainly used as carved glass etching agent, preservative, disinfectant, solvent for beryllium metal beryllium oxide, analytical reagent and surface treatment agent for silica steel plate, and also used in the manufacture of ceramic and aluminum-magnesium alloy oxidant and boiler feed system steam generation cleaning agent, organic synthesis fluorinating agent, electroplating solution, reagent for extracting rare elements.
