摘要
This invention relates to a process for the preparation of ultra pure, porous alumina powder comprising the steps of cleaning and refining a aluminium metal surface, followed by washing the refined surface, subjecting the washed surface to a treatment with aqueous Hg+2 solution followed by washing to remove excess Hg+2 ions, to obtain the nascent aluminium surface, and subjecting the same to treatment with cooled water vapour to obtain the alumina powder.
