Grain growth stagnation in fully dense nanocrystalline Y2O3 by spark plasma sintering. [PDF]

, 2010
Nanocrystalline (nc) Y2O3 powders with 18nmcrystallite size were sintered using spark plasma sintering (SPS) at 1100 ◦C and 100MPa for different durations. Specimens with 98% density and 106±33nm mean grain size were formed after 20 min.

Effects of dispersion surfactants on the properties of ceramic – carbon nanotube (CNT) nanocomposites [PDF]

, 2014
Gum Arabic (GA), Sodium Dodecyl Sulfate (SDS) and their mixture were used for the dispersion of multi-walled carbon nanotubes (CNTs) in an alumina matrix. A good dispersion at low loadings (0.5-1 wt%) of CNTs in alumina was achieved by an ultrasonic bath
