Abstract
We investigated the rheological properties of the slurries prepared through the planetary mixer. The planetary mixing enhanced the fluidity of the slurry for a short time. For a long time mixing, however, a film was observed on the surface of the slurry like the Ramsden phenomena, because the temperature of the slurry elevated by planetary mixing. The slurry containing the film showed high viscosity. The slurry prepared by ball milling after planetary mixing had lower viscosity than that prepared by an only ball milling.
