TiO2 hollow spheres with different diameters(200～500 nm) and tailored shell thickness(25～100 nm) have been successfully prepared using hydrophilic colloidal carbon spheres as template and TBT(tetrabutyl titanate) as precursor.

Synthesis of spherical titania by hydrolysis using industrial titanium sulfate solution

In this paper we studied the optimize process to prepare the spherical titania by surfactant-aided sol-get methods, sheet bismuth oxide chlorine by precipitation and composite of TiO_2/BiOCl by solid-phase method through the Near-Infrared reflectance spectroscopy, respectively.

Study on fracture mechanism of alumina bubble ceramic;

The lightweight alumina ceramic was prepared with alumina bubble and α-Al 2O 3 powder, and solution of Al 2(SO 4) 3· 18H 2O and NH 4Al(SO 4) 2·12H 2O and PVA as the cement, which will form in situ the nano γ-Al 2O 3 particles, to decreasing the sintering temperature as sintering agent, and improving the strengthen of the ceramics.

A wet chemical method was cidopted to introduce alumina sol to surface-modification of alumina bubble and in-situ decomposition characteristics, distribution of alumina sol, mi-crostructure and mechanical properties of surface-modified alumina bubble were studied by SEM, XRD, Coulter LS Particle Size Analyzer and self-preparation experimental device for measurement of compressive resistance.
