张少明, 胡双启, 张瑞芬, et al. Solvation and Separation of the Preparation Process of α-Al2O3 Precursor Nano Powder by Precipitation[J]. 2008, 29(6): 542-545.DOI:
The conditions of preparing nanometer α-Al2O3 powders by chemical method were discussed
and the solvation and separation of gel aluminum hydroxide in the process was studied.Not only the influence of solvation on filtration velocity
but also the best technique conditions were obtained.TEM
XRD and IR were used to characterize the particle shape
phase and size distribution.It is found that the solvation degree is decreased obviously by absolute ethyl alcohol
and the filter velocity is increased.The obtained powder is fibrous α-Al2O3 with the average particle diameter of 59.3 nm with good dispersion and epigranular.
