摘要：

The influence of the gel composition on the dimensions of AlPO4-5 crystals formed in the system Al2O3:P2O5:(C2H5)3N:H2O:H2SO4 has been studied systematically. A linear correlation between the water content of the reacting gel and both the maximum length and the aspect ratio of the crystals has been found, whereas amine as well as P2O5 contents are controlling the nucleation process. Crystals with sizes ranging from 20-mu-m to about 750-mu-m along the hexagonal c-axis can be synthesized with good yields when these correlations are used.
