The in situ formation of nanostructured aluminum hydroxides on the surface of alumina particles, which can work as inorganic binder, was reported in this paper. The effect of the suspension pH during milling of alumina powder and subsequent hydrothermal treatment for the hydroxide formation and microstructure was depicted. Under acidic pH condition, the formation of hydroxides was not observed.

Aluminium Hydroxide [Al(OH) 3] is mostly used as a flame retardant filler in the wire and cable, construction and friction industry. Our grades offer not only technical properties like ultra fine particles, very narrow particle size distributions and platelet-like morphologies, but also high specific surface areas.

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 …
