(D) Commercial high-purity alumina nanopowder is manufactured from aluminum metal and alcohol, producing high-purity aluminum alkoxide, after which hydrated alumina is produced by the hydrolysis of aluminum alkoxide, with consequent calcination [11] (Sumitomo Chemical).
Pure hydrated alumina as a cement substitute can quell alkali-silica reactivity (ASR) in cured concrete, say Tiffany Szeles, Farshad Rajabipour and Shelly Stoffels, The Pennsylvania State University, State College, Pa., and Jared Wright, Walker Restoration Consultants, Seattle, in their technical paper, Mitigation of Alkali-Silica Reaction by Al[(OH).sub.3] [alumina].
The alumina present in the sodium chromate solution was removed by adding sodium dichromate solution by maintaining the pH at about 9, sodium dichromate caused the hydrated alumina to crystallize.
In this process alumina is dissolved out of bauxite and then crystalized via cooling, producing a pure form of hydrated alumina. This hydrated alumina is very abrasive and can cause severe erosion as it passes through heat exchangers, which contain multiple cooling plates.
