Aluminum Fluoride

   Also found in: Wikipedia 0.01 sec.
aluminum fluoride [ə′lüm·ə·nəm ′flu̇r‚īd]
(inorganic chemistry)
AlF3·3½H2O A white, crystalline powder, insoluble in cold water.

Aluminum Fluoride 

(A1F3), a salt; colorless crystals with a density of 3,100 kg/m3. It sublimates upon heating. It is only very slightly soluble in water (0.559 g in 100 g H20 at 25°C) and does not react with alkalies or acids (except boiling sulfuric acid). Aluminum fluoride forms numerous complex compounds—for example, Na3AlF6, so-called cryolite, which is widely used in the aluminum industry. Aluminum fluoride can be obtained by passing HF over Al or A1203 at red heat or by other methods. It is used as a component part of an electrolyte used for obtaining and purifying aluminum.

Also among the ventures is infrastructure development, including building a new phosphate export terminal at the industrial city south of Aqaba to replace the current facility, in addition to a number of projects now under study, namely uranium ore extraction and aluminum fluoride production plants.
While low cost commodity products such as aluminum fluoride and cryolite benefit from an expanding global aluminum industry, high priced inorganic fluorine gases ate finding increasing use in etching and cleaning applications in the electronics industry.
[14] The project also included an aluminum fluoride plant with an annual production capaci ty of 12,000 tons.
