摘要： Nano-sized metal-bearing powders and doped-powders are synthesized by means of a process whereby a non-volatile metal-bearing precursor powder or powder mixture is dispersed in a hot gas stream at relatively low temperatures. A first volatile reactant is added, converting the metal in the precursor into a volatile metal compound. Subsequently a second volatile reactant is injected into the gas stream, converting the volatile metal compound into a solid, which condenses as a nano-sized metal-bearing powder upon quenching. Finally, the vapour/metal-bearing powder mixture is separated from the gas stream.

摘要： This invention pertains to a process for producing ultra-fine rutile titanium dioxide powders. This particular compound is useful as UV-blocker in paints, plastics, coatings, pigments and sunscreens. The new process comprises the steps of providing a hot gas stream and of introducing therein firstly: - a titanium-bearing first reactant; and - a carbon- and/or nitrogen-bearing second reactant; the temperature of said gas stream being chosen so as to vaporize said first and second reactants, these being selected so as to form, at the prevalent temperature, titanium carbide, titanium nitride or a mixture thereof, as a nano-sized precursor; and, thereafter: - a volatile oxygen-bearing reactant selected so as to react with the nano-sized precursor, converting it to nano-sized titanium dioxide powder having a rutile content of at least 50%. This reaction scheme allows for the manufacture of powders with or without doping elements with a primary particle size between 1 and 100 nm.

摘要： The present invention relates to doped ceria (CeO2) abrasive particles, having an essentially octahedral morphology. Such abrasives are used in water-based slurries for Chemical Mechanical Polishing (CMP) of subrates such as silicon wafers. The invention more particularly concerns yttrium-doped ceria particles having a specific surface area of 10 to 120 m2/g, characterized in that at least 95 wt%, preferably at least 99 wt%, of the particles are mono-crystalline and in that the particles' surfaces consist of more than 70 %, preferably of more than 80 %, of planes parallel to {111} planes. A novel gas phase process for synthesizing this product is also disclosed, comprising the steps of providing a hot gas stream,- and, introducing into said gas stream a cerium-bearing reactant, a dopant-bearing reactant, and an oxygen-bearing reactant,- the temperature of said gas stream being chosen so as to atomize said reactant, the reactant being selected so as to form, upon cooling, doped ceria particles. Abrasive slurries based on the above ceria offer a low level of induced detectivity in the polished substrate, while ensuring a good removal rate.
