The effect of Al3+ concentration on the properties of alumina powders obtained by reaction between aluminium sulphate and urea in boiling aqueous solution
(Elsevier Sci Ltd, 2002)Homogeneous precipitation of alumina precursors was carried out in boiling aqueous solutions that contained excess urea and 0.010 0.200 M Al3+. The obtained precursor precipitates were dried for 2 h at 100 C to yield ... -
Thermal behaviour of alumina precursor obtained by the aluminium sulphate-urea reaction in boiling aqueous solution
(Elsevier Sci Ltd, 2003)An aqueous solution containing 0.1 M Al3+ and excess urea was boiled for 4 h to obtain an alumina precursor precipitate. The precursor precipitate was separated into several portions and each portion was heated at a different ...
