Abstract
The present invention provides a cerium oxide particulate composition and a process for preparing a cerium oxide particulate composition comprising aggregates of approximately spherical primary particles of cerium oxide. The method involves preparing a solution of a cerium oxide precursor, aerosolizing the cerium oxide precursor solution, and heating the aerosol to provide the cerium oxide particle composition.
