    摘要： A process for reducing dissolution time in the production of sodium percarbonate particles containing an alkali metal silicate as stabilizer by fluidized bed spray granulation and/or by coating sodium percarbonate particles with a coating containing an alkali metal silicate, wherein a solution containing alkali metal silicate is sprayed during production and/or coating which contains alkali metal silicate having a modulus in the range from less than 3 to greater than 1. Sodium percarbonate produced by fluidized bed spray granulation is distinguished by elevated Oa stability and short dissolution times and may thus readily be used in detergents and cleaning products containing silicate builders.

    摘要： Provided is a process for preparing surface-modified silicon dioxide particles with a mean particle diameter of at most 100 nm, involving (A) high-pressure grinding of a predispersion having (i) surface-modified silicon dioxide particles which are at least partly aggregated, are bonded to the surface-modifying component via Si—O—Si bonds, and still have reactive groups on their surface; (ii) an organosilicon compound which has a silicon-carbon bond and a functional group which can react with the reactive groups to form a covalent Si—O—Si bond; and (iii) a solvent, to form a dispersion; and (B) removing the liquid phase of the dispersion. Also provided are redispersible, surface-modified silicon dioxide particles obtained by this process, and their use in toner powders, silicone rubber, adhesives, and scratch-resistance surface coatings.
