摘要:
Surface-modified, pyrogenically produced silicon dioxide is obtained by placing a pyrogenically produced silicon dioxide in a know mixing device, spraying it with a chemical compound from the group:CHF.sub.2 --CF.sub.2 --O--(CH.sub.2).sub.3 --Si(OCH.sub.3).sub.3CF.sub.3 --CHF--CF.sub.2 --O--(CH.sub.2).sub.3 --Si(OCH.sub.3).sub.3C.sub.4 F.sub.9 --CH.sub.2 --CH.sub.2 --Si(OCH.sub.3).sub.3C.sub.6 F.sub.13 --CH.sub.2 --CH.sub.2 --Si(OCH.sub.3).sub.3with intensive mixing, subsequently mixing it and tempering the mixture obtained for a fairly long time.
