In this study the synthesis of nanocrystalline zinc oxide powders using an oxidative electrodeposition method without the use of any surfactants or stabilizers was explored. Nanocrystalline zinc oxide powders were successfully produced by this method and characterized and the effect of the process parameters was studied. The experimental results and analyses were validated against a proposed mechanism for particle formation during oxidative electrodeposition. It was demonstrated that the proposed mechanism can describe the process accurately. © 2009 IOP Publishing Ltd.

The chemical vapour synthesis (CVS) route is a versatile process that can be used for the synthesis of nanocrystalline ceramics with very small crystallite sizes having a narrow particle size distribution. In this study, a CVS technique was used to prepare nanocrystalline titania from tetraisopropyl orthotitanate at a processing temperature of 1273 K (1000 °C). High resolution transmission electron microscopy, x-ray diffraction and nitrogen adsorption techniques were used for the characterization of the as-synthesized powders. Green bodies were produced by a combination of uniaxial and cold isostatic pressing, which were then sintered. A simple pressureless sintering route was established that led to the production of a dense titania ceramic with a uniform microstructure and an average grain size well in the nanophase regime. © 2006 IOP Publishing Ltd.
