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
