Surface properties of nanoceramic powders

Abstract

The paper focuses on selected fragment of nanopowders surface studies made by author. The studies presented consist of viscosity measurements of ceramic slurries and ionic conductivity and pH determination of supernatants obtained by using of nanozirconia suspensions centrifugation. Three different nanozirconia powders were chosen to compare the influence of D-fructose on the viscosity of nano-ZrO 2 suspensions. Then the powders were centrifuged with water to leach soluble counter-ions. It was proved that the leaching has a SIGNIFICANT effect on the viscosity of nano-ZrO 2 suspension.
