Abstract
Disclosed herein is a method of deagglomerating ceramic powder to inhibit agglomeration and provide a uniform particle size, a deagglomeration mill used for the above method, and a method of preparing uniformly mixed ceramic slurry using the deagglomerated ceramic powder. The deagglomeration method of the ceramic powder includes loading a mixture of ceramic powder and solvent into the deagglomeration mill which includes a hollow cylindrical mill cover having a diameter larger than a length and having a plurality of beads therein; rotating an impeller of a main shaft disposed longitudinally at an internal center portion of the mill cover at a peripheral velocity of 6–10 m/s, using a driving means; deagglomerating the ceramic powder by the action of beads which are moved by a rotational force of the impeller; and discharging the mixture of ceramic powder and solvent from the deagglomeration mill.
