Project Report from the year 2006 in the subject Materials Science, grade: Sehr Gut, Brandenburg Technical University Cottbus (Lehrstuhl Aufbereitungstechnik), language: English, abstract: Rapid development of technologies requires introduction of new materials as well as improvement of the existing one (Kudyba-Jansen et al. 2000). The very fine fumed metal oxide γ - Al2O3 (d50 = 0.13nm, Desussa, Germany) has been investigated on the possibilities for development of green bodies though the innovative wet shaping process gel casting. Thus, this study in particular is focused on characterisation of the suspension stabilities promoted by two commercially produced polyelectolytes Dolapix CE64 and Dolapix A88 (Zschimmer-Schwarz, Lahnstein, Germany). The optimal dispersant dosage has been found and the suspension stability has been further evaluated. Finally Dolapix CE64 has been found to be most favourable for enhancing the stability of aqueous γ - Al2O3.
