As mentioned before, this compound has the chemical formula of AlF3 . Aluminium Fluoride Uses in Aluminium Manufacturing. Hydrofluoric acid, long known to be effective at removing certain contaminants, has not been used to dissolve aluminum fluoride on aluminum-containing surfaces because the hydrofluoric acid strongly attacks such surfaces, and consequently damages … In the gas form, aluminium fluoride has the form of trigonal molecules of D3h symmetry. Aluminium fluoride has the 3 dimensional polymeric chemical structure, so that it has the high melting point level. You can also find the non-hydrate form of aluminium floruide in the mineral like oskarssonite. Aluminium fluoride plays an important role in the aluminium manufacturing process. In the same time, aluminium fluriode can form the purer aluminium product from this production process. It is also included to create refractory ceramic products. In that process, aluminum is extracted from one of its compounds (usually aluminum oxide) by passing an electric currentthrough the molten (melted) compound. Aluminum fluoride’s insolubility with strong acids should prevent storage with such acids in close containment. The addition of aluminum fluoride to the raw materials used in the process reduces the temperature at which the reaction occurs and improves the conductivity of the molten compound. In the form of a white powder, Aluminum Fluoride occurs naturally as minerals rosenbergite and oskarssonite. Disclaimer | our customers so that we exceed their requirements.

Aluminum fluoride is white crystals that sublimes (760 mm) at approximately 1272 degrees Celsius. First bauxite (a clay like soil and the world’s main source of aluminum) is mined and chemically refined to produce aluminum oxide (alumina). This amount will be based on the smelter technology used by the respective producers. Aluminium fluoride can also be used as the flux ingredient which can remove the magnesium in the refining process of aluminium scrap. Potassium Aluminum Fluoride is a commercial purity fused inorganic salt. Unlike aluminium fluoride, these aluminium trihalides has the low melting point and easily evaporate to release dimers. About 41,200, 4,700, and 13,200 tons of byproduct fluorosilicic acid were sold for water fluoridation, AlF3production for the aluminum industry, and for other uses, such as sodium silicofluoride production, respectively.
