From page 73...
... Nanophase ceramics, with their high grain-boundary purity and small particle size, leading to higher reactivity among grains and shorter and more effective diffusion paths, are expected to sinter at lower temperatures than normally available ceramics. They are also expected to exhibit considerably improved sinterability and mechanical properties, owing to a lack of brittle second phases in their interfaces and more effective crack-energy dissipation via their ultrafine grain-boundary networks.
