Densification of Monodisperse Iron Nanoparticles from a Colloidal Dispersion at Moderate Heating Rates and Temperatures
Digital Object Identifier (DOI)
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 nonplanar or fragile substrates. Additionally, large areas can be processed in parallel.
