摘要：
Gibbsite (Al2O3 3H2O) powder. used for alumina powder production. can be prepared by the decomposition of sodium alum inate solutions induced by dilution or partial neutral ization, This decomposition process exhibits an incubation period and instability or non-reproducibility in reaction kinetics, UV time-scanning spectra and Raman spectra change have been measured to investigate the solution in incubation period and the factors affecting the grain size of gibbsite precipitate
