Physicochemical Property of Ammonium fluoride powder

• Colorless leafy or needle-like crystals, hexagonal columnar crystals after sublimation.Ammonium fluoride Raw Materials is easily deliquescent. Soluble in water, aqueous solution is acidic. Soluble in alcohol, insoluble in acetone and liquid ammonia.
• Ammonium fluoride CAS 12125-01-8 , chemical formula NH4F, molecular weight 37.04, colorless transparent hexagonal crystals or granular powder, toxic, easily deliquescent. Decompose when heated. Specific gravity 1.009(25℃). Soluble in cold water, ethanol.

Ammonium fluoride powder decomposes into ammonia and hydrogen fluoride when heated. Aqueous solution is acidic reaction, can corrode glass, corrosive to skin. Ammonium fluoride powder decomposes into ammonia and ammonium hydrogen fluoride (NH4HF2) in hot water.Ammonium fluoride powder evaporates when the aqueous solution releases ammonia and becomes acidic, and the finished product of ammonium fluoride is not available.

Ammonium fluoride Raw Materials forms insoluble fluoride with magnesium, calcium, thorium and rare earth metals. Forms tetrafluoro or hexafluoro compounds with most transition metals. Ammonium fluoride Raw Materials is used for etching glass, wood preservation, fabric mordanting and dyeing, also used as disinfectant and analytical reagent.

Production methodprocess of Ammonium fluoride powder

Liquid-phase methodIn a lead or plastic container, put in a quantitative amount of hydrofluoric acid. Water is used to cool outside the container, and ammonia is slowly introduced under stirring until the Ph value of the reaction solution reaches about 4. The reaction liquid is crystallized by cooling, centrifugal separation and air drying, and Ammonium fluoride CAS 12125-01-8 is produced. its NH3+HF→NHF
