Abstract

The present invention provides 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. The present invention also provides a method of producing a ceramic green sheet, and a method of producing a multilayer ceramic electronic part. A method of producing ceramic slurry for use in manufacturing a ceramic electronic part comprises a mixing disintegration step in which a mixture of a ceramic powder and a dispersion solvent is subjected to an impact force-type dispersion method under a pressure of 100 kg/cm<SP>2</SP> or more so that the ceramic powder is disintegrated to a desired state and dispersed to obtain mixed and disintegrated slurry; and a dispersion step by a shear stress-type high-pressure dispersion method in which the mixed and disintegrated slurry is passed through a predetermined passage under a high pressure of 100 kg/cm<SP>2</SP> or more at a flow rate which can apply a maximum shear stress of 1000 Pa or more or a wall shear rate of 10<SP>6</SP> (l/s) or more to the ceramic powder.
