Abstract: A method of forming a powder and/or discrete gel particles of a compound selected from the group of a metallic oxide, a metalloid oxide, a mixed oxide, an organometallic oxide, an organometalloid oxide, an organomixed oxide resin, and/or an organic resin from one or more respective organometallic precursor(s), organometalloid precursor(s) and/or organic precursors and mixtures thereof, comprising the steps of passing a gas into a means for forming excited and/or unstable gas species (1a), typically an atmospheric plasma generating means; treating said gas such that upon leaving said means the gas comprises excited and/or unstable gas species which are substantially free of electrical charges at a temperature of between 10° C. and 500° C. A gaseous and/or liquid precursor is then introduced (50a,50b) into said excited and unstable gas species in a downstream region external (20) to the means for forming excited and/or unstable gas. The interaction between the precursor and the excited and unstable gas species results in the formation of a powder and/or discrete gelled particles which are subsequently collected. The particles prepared by the method may be subsequently functionalised.

Abstract: This invention relates to a method of functionalising a powdered substrate. The method comprises the following steps, which method comprises passing a gas into a means for forming excited and/or unstable gas species, typically an atmospheric pressure plasma or the like and treating the gas such that, upon leaving said means, the gas comprises excited and/or unstable gas species which are substantially free of electric charge. The gas comprising the excited and/or unstable gas species which are substantially free of electric charge is then used to treat a powdered substrate and a functionalising precursor in a downstream region external to the means for forming excited and/or unstable gas, wherein neither the powdered substrate nor the functionalising precursor have been subjected to steps (i) and (ii) and wherein said functionalising precursor is introduced simultaneously with or subsequent to introduction of the powdered substrate. Preferably the method takes place in a fluidised bed.
