Characterization of CeO2 Ultrafine Particles Prepared Using a Thermal Relaxation Technique

Abstract
Cerium(IV) oxide ultrafine particles were prepared in a nylon 11 matrix through a relaxative auto-dispersion (RAD) process. High-resolution electron microscope (HREM) observations revealed that the lattice parameter and mean particle size of CeO2 ultrafine particles were 0.541 nm and 4.1 nm, respectively.
