Pyrogenically prepared silica doped with silver or silver oxide is prepared by feeding an aerosol into a flame such as is used for the preparation of pyrogenic silica, mixing the aerosol homogeneously with the gas mixture before the reaction, then allowing the aerosol/gas mixture to react in a flame and separating the resulting pyrogenic silicas doped with silver or silver oxide from the gas stream in a known manner. The pyrogenic silica doped with silver or silver oxide by means of an aerosol can be used as a bactericidal filler.
