With the formula AlF 3 ·xH 2 O, these compounds include monohydrate (x = 1), two polymorphs of the trihydrate (x = 3), a hexahydrate (x = 6), and a nonahydrate (x = 9). [10] The majority of aluminium fluoride is produced by treating alumina with hydrogen fluoride at 700 °C: [4] Hexafluorosilicic acid may also be used make aluminium fluoride. [11]
aluminium fluoride: 7784–18–1 AlI 3: aluminium iodide: 7784–23–8 AlN: aluminium nitride: 24304–00–5 Al(NO 3) 3: aluminium nitrate: 13473–90–0 Al(OH) 3: aluminium hydroxide: 21645–51–2 AlP: aluminium phosphide: 20859–73–8 AlPO 4: aluminium phosphate: 7784–30–7 AlSb: aluminium antimonide: 25152–52–7 Al 2 O 3 ...
Fluoride mimics the nucleophilic hydroxide ion in these enzymes' active sites. [41] Beryllium fluoride and aluminium fluoride are also used as phosphatase inhibitors, since these compounds are structural mimics of the phosphate group and can act as analogues of the transition state of the reaction. [42] [43]
Molten cryolite is used as a solvent for aluminium oxide (Al 2 O 3) in the Hall–Héroult process, used in the refining of aluminium. It decreases the melting point of aluminium oxide from 2000–2500 °C to 900–1000 °C, and increases its conductivity [18] thus making the extraction of aluminium more economical. [19]
aluminium monochloride: 13595-81-8 AlClF: aluminium chloride fluoride: 22395-91-1 AlCl 2<F: aluminium chloride fluoride: 22395-91-1 AlClO: aluminium chloride oxide: 13596-11-7 AlCl 2 H: dichloroalumane: 16603-84-2 AlCl 3: aluminium chloride: 16603-84-2 AlCl 2 F: aluminium chloride fluoride: 13497-96-6 AlCl 3: aluminium trichloride: 7446-70-0 ...
Aluminium monofluoride, also known as fluoridoaluminium, is the chemical compound with the formula AlF. This elusive species is formed by the reaction between aluminium trifluoride and metallic aluminium at elevated temperatures but quickly reverts to the reactants when cooled. [ 1 ]
Because the fluoride anion is highly basic, many alkali metal fluorides form bifluorides with the formula MHF 2. Sodium and potassium bifluorides are significant to the chemical industry. [ 2 ] Among other monofluorides, only silver(I) [ 3 ] and thallium(I) [ 4 ] fluorides are well-characterized.
Often, the metal (such as aluminium, iron, or copper) must be powdered because many metals passivate by forming protective layers of the metal fluoride that resist further fluoridation. [7] The alkali metals can react with fluorine explosively, while the alkaline earth metals react not quite as aggressively.
