Abstract
The invention relates to a method for producing powder particles that are uniformly coated with functional groups. According to said method, a suspension of particles of a crude powder is reacted with a coating reagent that contains at least one functional group. The suspension is homogenised in an agitation mill, where the particles are reacted with the coating reagent. The powder thus obtained is suitable for use as a filler in dental materials, cosmetic compositions, pharmaceutical compositions, paints, coatings, rubber mixtures and adhesives.
