Densification of Monosdisperse Iron Nanoparticles from a Colloidal Dispersion at Moderate Heating Rates and Temperatures
Published online by Cambridge University Press: 26 February 2011
Abstract
This work reports on the densification of iron nanoparticles heated at moderate rates without applied pressure as observed by TEM imaging, gas adsorption pore size measurement, and X-ray diffraction. Despite a low packing density, the small pore size is amenable to significant densification by pressureless sintering. Carbon residues from the stabilizing ligands affect both the composition and processing of the particles. This approach is amenable to deposition on non-planar or fragile substrates. Additionally, large areas can be processed in parallel.
