Ammonium aluminum fluoride

Aluminum fluoride is made by heating ammonium hexafluoroaluminate to red heat in a stream of nitrogen by the action of fluorine or hydrogen fluoride gas on aluminum trihydrate at high temperatures, followed by calcining the hydrate formed by fusing cryolite or sodium fluoride with aluminum sulfate or by a reaction of fluosilicic acid on aluminum hydrate (HSDB 1995).

The third method is a process developed by Central Glass Co. Ltd using the gas-solid reaction of ammonium complex of metal fluoride with fluorine [35]. Metal fluorides of Fe, Ti, Al, Cr, Mn, and so on can be used, however, aluminum fluoride seems the best from the viewpoints of cost and ease of handling. The reactions are supposed to take place at two stages as described below. [Pg.631]

In the UKF process hexafluorosilicic acid is reacted with ammonia to ammonium fluoride and silica. After silica removal, the ammonium fluoride solution is reacted with double its molar quantity of aluminum oxide hydrate to a mixture of ammonium aluminum hexafluoride (ammonium... [Pg.139]

In variants of this process, the ammonium fluoride is first reacted with sodium hydroxide to ammonia and sodium fluoride and then with aluminum fluoride to cryolite. After separation, the cryolite is calcined at 500 to 700°C. In the... [Pg.140]

Ammonium hydrogen fluoride is used for the dissolution of silicate minerals in the extraction of crude oil, for the pretreatment of aluminum prior to anodization and as a frosting agent in the glass industry. [Pg.141]

Derivation Aluminum fluoride, ammonium fluoride, and potassium chloride. [Pg.1026]

AMMONIUM ACID FLUORIDE (1341-49-7) F2H H4N Reaets with water, forming a weak solution of hydrofluorie aeid. Violent reaction with bases, releasing ammonia gas. Attacks glass, cement, and most metals in the presence of moisture. Upon contaet with moisture and metal, this material may release flammable hydrogen gas which may collect in enclosed spaees. Do not use aluminum, nickel, or steel containers. When heated to decomposition, emits toxic and corrosive fumes of ammonia, hydrogen fluoride, and nitric oxides. [Pg.67]

A well-formulated product will ensure a level of fluoride in the saliva above 0.02 ppm for several hours [18]. Fluoride ions are present in toothpaste formulations largely in the form of stannous fluoride (Snp2), sodium monofluorophosphate (NajPOsF), and sodium fluoride (NaF). But we can also find in the literature potassium fluoride, lithium fluoride, aluminum fluoride, zinc fluoride, acidic phosphate fluoride, ammonium fluoride, titanium tetrafluoride, and amine fluoride.

The formation of halides from olefins was studied in the special case of the introduction of fluorine. The combination of ammonium hydrogen fluoride and N-halosuccinimide is a relatively safe, easily manipulated reagent. The sluggish reactions can be improved by impregnation of the reagent on porous aluminum fluoride and sonication of the suspension (Eq. 6). ... [Pg.118]
