Abstract: New oxide particles (I) comprise a core, a doping component distributed in the core and a shell surrounding the core, where the core, doping agent and shell have different chemical compositions. An Independent claim is included for the preparation of (I), by doping the core, then coating the doped core.

Abstract: A pyrogenic process is used to prepare alkali-doped silica particles. Particles produced by this process exhibit homogeneous doping, reduced agglomeration, greater stability and higher removal rates. Aqueous dispersions containing alkali-doped pyrogenic silica with average particle size less than 100 nm are used for polishing surfaces (CMP).
