Precipitation of finely divided Al2O3 powders by a molten salt method
Abstract
Finely divided Al2O3 powders have been prepared by reactions of Al2(SO4)3 or AlCl3 with molten nitrates, nitrites or nitrates containing Lux–Flood bases. The reactions in different melts were compared and the possible stoichiometries of the reactions have been proposed. The powders precipitated were characterised by XRD, AAS and TEM.
