  • Publication number: 20230041600
    Abstract: The disclosure relates to cerium based particles having a rough surface and their use as a component of a polishing composition, especially for chemical mechanical polishing. The cerium based particles have substantially the shape of polyhedrons which have one or more faces with protrusions thereon, said protrusions being integrally formed with said cerium based particles. The present disclosure also relates to the method of preparation of the cerium based particles.

  • Publication number: 20230002639
    Abstract: The invention relates to cerium based core-shell particles having a core of cerium oxide optionally doped with at least one metal (M) and a shell consisting of a plurality of nanoparticles of cerium oxide optionally doped with at least one metal (M?), which can be the same or different from metal (M), formed on the surface of the core particle. The invention also relates to dispersions thereof in a liquid medium, to a process for producing the same and to the use of these particles and dispersions in polishing applications such as chemical mechanical polishing.
