Einsatz unterschiedlicher Rührwerkskugelmühlen für die Erzeugung von Nanopartikeln

Abstract: EinleitungNanopartikel erschließen aufgrund ihrer außer-gewöhnlichen Eigenschaften immer mehr Anwendungsfelder in den unterschiedlichsten Industriezweigen. Außer durch chemische Synthese (Bottom-up-Verfahren) besteht die Möglichkeit, Nanopartikel durch Nasszerkleinerung in Rührwerkskugelmühlen (Top-downVerfahren) zu erzeugen. Zum Beispiel konnte Schmelzkorund in einer Rührwerkskugel-mühle in wässriger Phase auf unter 10 nm zerkleinert werden, wenn die Suspension elektrostatisch stabilisiert wird [2 -5, 7]. Sch… Show more

“…Again the suspension was stabilized electrostatically, but at this time different acids were used. The grinding result for different acids can be explained with the effects of chaotropic and kosmotropic ions following the Hofmeister series (Ló pez-Leó n et al, 2003; Breitung-Faes and Kwade, 2006). Clear water has a well classified structure.…”

“…The rate constant k is strongly dependent on the attrition intensity . A search for methods for more efficient attrition brought us to the pigment and coating industries, which have long experience in the grinding of solids, both on small and large scale . One of the devices that is often used for this purpose is a so-called bead mill (see Figure ).…”
