Beschreibung
Zusammenfassung:	The invention relates to a method for modifying the surface of powdery particles by means of silane compounds. According to the invention, in order to perform the method economically, said method comprises the steps of introducing the powdery particles into a reaction mixture comprising a silane component and a liquid alcoholic component, wherein the liquid alcoholic component comprises an alcoholic reactive component, and then chemically reacting the silane component and the alcoholic reactive component in the presence of the particles, wherein reaction products formed during the reaction are deposited on the surface of the particles, a primary particle preparation thus being formed.
