Аннотация:A chemical method with reaction of aluminum alloy D16 and aqueous sodium hydroxide solution is used to prepare very fine aluminum hydroxide powder. It is established by x-ray phase analysis that the powder obtained consists of three aluminum oxide modifications: gibbsite, boehmite, and bayerite. It is shown by laser diffraction that within an aluminum oxide suspension there is extensive bimodal distribution of particle size distribution (0.4 – 190 μm). The powder obtained is a precursor for preparing aluminum oxide ceramic.
