The master sintering curve for pressure-less sintering of TiO2

Master sintering curve for Gd-doped CeO2 solid electrolytes

The sintering behavior of gadolinia-doped ceria powders was studied by the master sintering curve (MSC). Dilatometric analyses of powders produced by a soft chemical method were performed to provide the experimental data set for the construction of the MSC. The assumed model provided good fittings of the MSC and the activation energy for the sintering of Ce1-xGdxO3-d, with x = 0, 0.05, 0.1, and...

Effects of phase and doping on flash sintering of TiO2

Sintering Rate and Mechanism of TiO2 Nanoparticles by Molecular Dynamics.

Titania is the dominant white pigment and photocatalytic material, a key component of sunscreens and has promising applications in photovoltaics and sensors of organic vapors. The growth of TiO2 nanoparticles by sintering, the critical step during their large scale manufacture and processing, is elucidated and quantified by molecular dynamics. Highly mobile ions from the particle surface fill i...

Sintering of Fine Oxide Powders: II, Sintering Mechanisms

Conventional and new sintering mechanisms have been porous compacts is well-known in the ceramic literature. However, several reports have been presented recently that investigated using fine powders of CeO2 and Y2O3 of excellent sinterability. We have verified the validity of Herring’s show that particle/grain size can remain essentially constant up to a density of 92%, and such a resistance t...
