Abstract
A method of producing ceramic slurry capable of producing uniformly dispersed ceramic slurry without excessively damaging a ceramic powder, and a method of producing a ceramic slurry composition used for producing a multilayer ceramic electronic part, from which an undissolved binder is precisely removed. Also provided is a method of producing a ceramic green sheet, and a method of producing a multilayer ceramic electronic part. A ceramic powder having an average particle diameter of about 0.01 to 1 &mgr;m is mixed with a dispersion solvent (solvent) and disintegrated by a medium-type dispersion method using a dispersion medium such as balls, beads, or the like to obtain mixed and disintegrated slurry, followed by high-pressure dispersion under a pressure of about 100 kg/cm or more. The ceramic slurry composition contains a ceramic powder, a dispersant, a binder, and a solvent, wherein a binder solution prepared by mixing a solvent and the binder to form a solution, and dispersing the binder under a high pressure of about 100 kg/cm or more is used as the binder to decrease the content of the undissolved binder.
