Abstract

Abstract: During the process of peptization and hydrothermal crystallization, the aggregation behavior and the resulting morphology of nanocrystalline titania (TiO₂) were studied by X-ray diffraction (XRD), scanning electron microscope (SEM), and dynamic light scattering (DLS) techniques. The results show that during peptization process the mixture of rutile-type and anatase-type primary particles with 10--15nm in diameter formed by peptizing the precipitated amorphous titania are transformed into rod-like secondary crystalline grains with sizes of (30--50)nm×(80--100)nm through an oriented aggregation mechanism, which obey a crystal face-matching rule. In the process of hydrothermal crystallization under 180℃, however, the rod-like secondary crystalline grains are first broken into nanoparticles with diameter in the range of 10--15nm (namely the same sizes as those of the primary particles), and the formed nanoparticles then grow in hydrothermal solution. The finally resulting particles with the sizes of 10--30nm (spherical anatase) and 20--60nm (rod-like rutile) are found to have a higher crystallization degree than the primary particles formed in the process of peptization.
