专利号:US-2005003744-A1 优先权日:2001-11-16 标题 :Synthesis of chemically reactive ceria composite nanoparticles and CMP applications thereof 发明人:FENG XIANGDONG; HER YIE-SHEIN; MAO YUN 权利人:FERRO CORP 摘要:The present invention provides a method of synthesizing nanosized abrasive particles and methods of using the same in chemical mechanical polishing slurry applications. The nanosized abrasive particles according to the invention are produced by hydrothermal synthesis. The crystallites of the particles include cerium atoms and atoms of metals other than cerium. In a preferred embodiment of the invention, the crystallites exhibit a cubic crystal lattice structure. The differences in electric potential between the cerium atoms and the atoms of metals other than cerium facilitate the polishing of films without the need for chemical oxidizers.
专利号:US-8790608-B2 优先权日:2008-09-12 标题:Siliceous materials having tunable porosity and surface morphology and methods of synthesizing same 发明人:HOLLAND BRIAN T; WELZ SASCHA 权利人:HOLLAND BRIAN T; WELZ SASCHA; NALCO CO 摘要:Non-spherical siliceous particles having a plurality of porous branches are disclosed and claimed. The porous branches are randomly oriented and elongated, ring-like, and/or aggregated. An additive introduced during synthesis of the particles modifies pore volume and morphology. The tunability of the pore volume includes an inner diameter ranging from about 2 â„« to about 50,000 â„«. Synthesizing the particles includes mixing under constant or intermittent stirring in a reaction vessel an aqueous silicic acid solution with an acidic heel solution to form a mixture. The stirring may optionally be performed at a variable speed. An additive is introduced into the mixture at a controlled rate, wherein the additive imposes a pH change from a lower pH to a higher pH to the mixture to induce siliceous particle precipitation. Optionally, a metal dopand may be introduced into the particles and/or at least a portion of an outer surface located outside of the pores and/or an inner surface located inside of the pores may be modified.
专利号:WO-9827010-A1 优先权日:1996-12-16 标题:Synthesis of aluminium and titanium compounds 发明人:KEMMITT TIMOTHY 权利人:IND RES LTD; KEMMITT TIMOTHY 摘要:The invention relates to a method for preparing an aluminium- or titanium-containing complex or complexes from an aluminium or titanium source respectively comprising reacting the aluminium or titanium source with a solvent consisting essentially of aminoalcohol(s). The products of the method may be used to prepared industrially-useful materials, such as ceramics.
专利号:US-7943116-B1 优先权日:2008-01-24 标 题 :High-yield synthesis of brookite TiO2 nanoparticles 发明人:HUBER DALE L; MONSON TODD C 权利人:SANDIA CORP 摘要:A method for forming non-agglomerated brookite TiO 2 nanoparticles without the use of expensive organic surfactants or high temperature processing. Embodiments of this invention use titanium isopropoxide as the titanium precursor and isopropanol as both the solvent and ligand for ligand-stabilized brookite-phase titania. Isopropanol molecules serve as the ligands interacting with the titania surfaces that stabilize the titania nanoparticles. The isopropanol ligands can be exchanged with other alcohols and other ligands during or after the nanoparticle formation reaction.
