Specifics of high-temperature coarsening of ceria nanoparticles

Particle coarsening trends at high temperatures (200 to 700 A degrees C) in CeO2 nanoparticles having various chemical histories are determined by powder X-ray diffraction (XRD), low-temperature nitrogen adsorption, transmission electron microscopy, and small-angle neutron scattering (SANS). Intergrowth of individual CeO2 crystallites is the main scenario of nanoparticle coarsening.
