One Step

Nanocomposite particles of anatase-type titania (TiO2) and cubic/tetragonal zirconia were synthesized from hydrothermal processing of TiCl4 and ZrOCl2·8H2O or ZrCl4 alcohol solutions at 160–200 °C. It was found that the morphologies and composition of the composite particles were mainly controlled by the precursors and the sequence by which the precursors were added. The TiO2–ZrO2 composite particles with nanoscale uniformity can be obtained by solvothermal processing of TiCl4 or a ZrO2 precursor together with preformed ZrO2 or yttria stabilized zirconia (YSZ) nanoparticles in ethanol. A novel one-step and non-template method for preparing ZrO2–TiO2 core–shell structured composite particles with hollow interior was identified, and possible reaction mechanism was suggested.

Microstructural Examination

Yttria stabilized zirconia (YSZ) has become a significant technological material due to its high ionic conductivity, chemical inertness, and good mechanical properties. Temperatures on the order of 1700°C are required, however, to densify YSZ to the degree necessary for good electrical and mechanical properties. A technique for lowering the densification temperature is the addition of small amounts of material which facilitate the formation of a liquid phase at comparatively low temperatures. In this study, sintered microstructures obtained from the use of Al2O3 as a sintering aid were examined with scanning, transmission, and scanning transmission microscopy (SEM, TEM, and STEM).
