The significant role played by water in the mechanochemical synthesis of highly distorted aluminum hydroxide fluorides is on the main focus of this research paper. The importance of water in the synthesis was evaluated considering separately combinations of O/OH sources (Al(OH)3, Al2O3) and fluorine sources with or without structural water (β-AlF3.3H2O, …

which consists of 60% aluminium oxide as hydroxide (Al 2O 3 + H 2O), the rest are metal oxides (Fe 20 3, Si0 2, Ti0 2). The production process is complex and energy intensive and is mainly based on two steps that are briefly described in the following. Extraction of pure alumina (aluminium oxide, Al 2O 3) from bauxite Alumina recovery begins by ...

Sodium aluminate is manufactured by the dissolution of aluminium hydroxide (Al(OH)3) in a caustic soda (NaOH) solution. Aluminium hydroxide (gibbsite) can be dissolved in 20–25% aqueous NaOH solution at a temperature near the boiling point. The use of more concentrated NaOH solutions leads to a semi-solid product.

Similar mechanochemical transformation of alumina particles during milling has been reported. For an α-Al 2 O 3 powder ground in water at pH 8 using a high-energy stirred media mill, the amount of transformed aluminum trihydroxides increased with the milling time; after short milling (2 h) only bayerite (4.6%) was formed, but for longer milling times, gibbsite was also observed …
