TL;DR: In this article, the authors investigated the conductivity of high-density bulk-anatase samples with a grain size between 24 and 56 nm prepared by high pressure field-assisted sintering.
Abstract: We investigated the conductivity of high-density bulk-anatase samples with a grain size between 24 and 56 nm prepared by high pressure field-assisted sintering. When exposed to humid atmosphere, the insurgence of proton conductivity was observed for temperatures below 350 °C. Below this temperature, the samples showed a conductivity several orders of magnitude higher than that measured under dry oxygen atmosphere. The protonic conductivity strongly increased as grain size decreased, while a negligible dependence from porosity was observed when the latter ranged between 8 and 25 vol%. If compared with zirconia- and ceria-based nanomaterials with similar grain size, bulk nanometric anatase showed the highest low temperature protonic conductivity as well as the highest crossover temperature between dry and humid conduction behavior.

TL;DR: In this paper, the authors used a plasma assisted sintering (PAS) process to consolidate submicron size silicon nitride powders to >99% of the theoretical density (TD) at 1750 °C in less than 5 min with retention of the a phase and the sub-micron grain size, which is attractive for retention of fine-grained microstructures favorable for superplastic deformation.
Abstract: Using a Plasma Assisted Sintering (PAS) process, submicron size, silicon nitride powders were consolidated to >99% of the theoretical density (TD) at 1750 °C in less than 5 min with retention of the a phase and the submicron grain size. The silicon nitride powders were sintered with 5 wt.% Y2O3 and 5 wt.% Y2O3 + 5 wt. % MgAl2O4 additives. The PAS processing method for the silicon nitride additive mixtures is attractive for retention of fine-grained microstructures favorable for superplastic deformation. Post superplastic forming heat treatments to transform the α−Si3N4 to lath-like, creep-resistant β−Si3N4 is another feature of the present processing method.
