APPLICATION
Ammonium fluoride is commonly called "commercial ammonium fluoride".
The word "neutral" is sometimes added to "ammonium fluoride" to represent the neutral salt—[NH4]F vs. the "acid salt" (NH4HF2).
Ammonium fluoride is usually used in preference to the neutral salt in the etching of glass and related silicates.
This property is shared among all soluble fluorides.
For this reason ammonium fluoride cannot be handled in glass test tubes or apparatus during laboratory work.
Ammonium fluoride is also used for preserving wood, as a mothproofing agent, in printing and dying textiles, and as an antiseptic in breweries.
Ammonium fluoride is employed in a new hydrothermal synthesis of complex flourides NaHoF4 and NaEuF4 these interesting compounds have the fluorite structure and are important for solid-state lasers as well as for photoluminescence and magnetic characteristics.
The product was used to prepare Ce3F nanoparticles (NPs) which were further conjugated to photosensitizers along with Au NPs to improve singlet oxygen generation in photosensitizers.

Ammonium fluoride is used primarily for oil well acidification and metal processing.
Ammonium fluoride is also used in the production of electronic components.
Some cleaning products such as wheel, brick and concrete cleaners may contain ammonium fluoride.
Ammonium fluoride is a probe used for solid-state lasers as well as for photoluminescence and magnetic characteristics.
Areas where ammonium fluoride is used apart from laboratory studies; glass matting, wood preservatives, brewer's yeast, printing industry.
Ammonium fluoride is commonly called "commercial ammonium fluoride".
The word "neutral" is sometimes added to "ammonium fluoride" to represent the neutral salt.
As the acid salt contains a higher percentage of fluoride by mass, Ammonium fluoride is usually used in preference to the neutral salt in the etching of glass.
Ammonium fluoride is also used for preserving wood, as a mothproofing agent, in printing and dying textiles, and as an antiseptic in breweries.
DEFINITION
Ammonium fluoride is the inorganic compound with the formula NH4F.
Ammonium fluoride crystallizes as small colourless prisms, having a sharp saline taste, and is highly soluble in water.
Like all fluoride salts, ammonium fluoride is moderately toxic in both acute and chronic overdose.
Ammonium fluoride is a white crystalline solid.
Ammonium fluoride is soluble in water.
Ammonium fluoride is noncombustible.
Ammonium fluoride is corrosive to aluminum.
Ammonium fluoride is used in chemical analysis, in brewing, and as a preservative for wood.
Ammonium fluoride is a fluoride salt having ammonium (NH4+) as the counterion.
Ammonium fluoride is an ammonium salt and a fluoride salt.
Ammonium fluoride is a white crystalline solid.
Ammonium fluoride is soluble in water. It is noncombustible.
Ammonium fluoride is corrosive to aluminum.
Ammonium fluoride is used in chemical analysis, in brewing, and as a preservative for wood.
ammonium fluoride has been used in some consumer cleaning products.
Most ammonium fluoride is used in industrial applications and processes.
Ammonium fluoride (AF) is used primarily for oil well acidification and metal processing.
Ammonium fluoride is also used in the production of electronic components. Ammonium fluoride is sold as a solid or a liquid (water) solution.
Ammonium fluoride is a corrosive chemical and contact can severely irritate and burn the skin and eyes causing possible permanent eye damage.
Breathing ammonium fluoride can severely irritate and burn the nose, throat, and lungs, causing nosebleeds, cough, wheezing and shortness of breath.
Contact of ammonium fluoride with water or moist skin can release hydrofluoric acid, a very dangerous acid.
Ammonium fluoride crystals are hydroscopic (absorb moisture from the air).
They also sublime (vaporize without going into a liquid state).
Inhalation or ingestion of large amounts of ammonium fluoride can cause nausea, vomiting and loss of appetite.
Exposure to high concentrations or long term exposure to lower concentrations can cause fluoride poisoning with stomach pain, weakness, convulsions, collapse and death.
Ammonium fluoride can also cause deposits of fluorides in bones and teeth, a condition called fluorosis.
Symptoms of fluorosis may include pain, disability and discoloration of teeth.
Ammonium fluoride is produced for use in classical inorganic analyzes and pharmacopoeia analyses.
Ammonium Fluoride, CAS 12125-01-8 in bulk quantity.
In the form of a white crystalline solid, Ammonium Fluoride is extremely water soluble.
Ammonium Fluoride is Used in the electronic industry for producing components.
Ammonium Fluoride is Used in metal processing and oil well acidification.
Ammonium Fluoride is active in a new hydrothermal synthesis of complex fluorides NaHoF4 and NaEuF4.
These interesting compounds are important for solid-state well as for photoluminescence and magnetic properties.
This substance is commonly called "commercial ammonium fluoride".
The word "neutral" is sometimes added to "ammonium fluoride" to represent the neutral salt—[NH4]F vs. the "acid salt" (NH4HF2).
The acid salt is usually used in preference to the neutral salt in the etching of glass and related silicates.
Ammonium fluoride can be derived by neutralizing ammonia with hydrofluoric acid.
Ammonium fluoride crystallizes as small prisms, having a sharp saline taste, and is exceedingly soluble in water.
Ammonium fluoride decomposes silicates, and thus glass, on being heated with them, a property shared among all soluble fluorides.
For this reason Ammonium fluoride cannot be handled in glass test tubes or apparatus during laboratory work.
Ammonium fluoride also sublimes when heated—a property common among ammonium salts.
Ammonium fluoride adopts the wurtzite crystal structure, in which both the ammonium cations and the fluoride anions are stacked in ABABAB layers, each being tetrahedrally surrounded by four of the other.
There are NH...F hydrogen bonds between the anions and cations.
On passing hydrogen fluoride gas (in excess) through the salt, ammonium fluoride absorbs the gas to form the addition compound ammonium hydrogen fluoride (ammonium bifluoride).
Ammonium fluoride is a crystalline, noncombustible inorganic compound represented by the chemical formula NH4F or FH4N.
Ammonium fluoride is a fluoride salt with ammonium as the counterion and is corrosive to cement, glass, and most metals, including aluminum.
Physical Description
Ammonium fluoride is a white crystalline solid.
Ammonium fluoride is soluble in water. It is noncombustible.
Ammonium fluoride is corrosive to aluminum.
Ammonium fluoride is used in chemical analysis, in brewing, and as a preservative for wood.
Ammonium fluoride is COLOURLESS CRYSTALS OR WHITE POWDER.
Reactivity Profile
Ammonium fluoride reacts with water to form hydrofluoric acid, a source of fluoride ions.
Unlike other halide ions, the fluoride ion is quite reactive, acting as a weak base and participating in some unique reactions.
In particular, fluorides react strongly with compounds containing calcium, magnesium, or silicon ions, which means that solutions containing soluble fluorides are corrosive to both living tissue and glass.
Hydrofluoric acid can cause severe chemical burns and is one of the few materials that can etch glass.
Ammonium fluoride is also a toxic gas in its anhydrous form.
Crystal structure
Ammonium fluoride adopts the wurtzite crystal structure, in which both the ammonium cations and the fluoride anions are stacked in ABABAB... layers, each being tetrahedrally surrounded by four of the other.
There are N−H···F hydrogen bonds between the anions and cations.
This structure is very similar to ice, and ammonium fluoride is the only substance which can form mixed crystals with water.
Ammonium fluoride (NH4F) is manufactured and sold in solid form or in aqueous solutions.
The solid is a white, hydroscopic, crystal.
The solutions are clear, colorless liquids that have a slightly sharp, pungent odor.
Common industrial solution strength concentrations are 36-40% in water.
Ammonium fluoride appears as colorless phyllodes or needle-like crystals and forms hexagonal columnar crystals after being subject to sublimation.
Ammonium fluoride is easily deliquescent.
Ammonium fluoride is easily soluble in water with aqueous solution being acidic.
Ammonium fluoride is soluble in alcohol but insoluble in acetone and liquid ammonia.
