Manufacturing method of dielectric slurry and manufacturing method of multilayer capacitor

A method of manufacturing a dielectric slurry, comprising:

• spraying, by a plurality of spraying modules, dielectric slurry including dielectric particles supplied from a slurry supply module toward each other in a particle dispersing chamber, such that portions of the dielectric slurry sprayed from the plurality of spraying modules collide in the particle dispersing chamber;
• classifying, according to particle size and by a classifying module, the dielectric particles from the particle dispersing chamber into at least two groups;
• sending one of the at least two groups of the dielectric particles, as recovered dielectric particles, to the slurry supply module;
• sending another of the at least two groups of the dielectric particles, as dielectric particles of the manufactured dielectric slurry, to a slurry storage;
• and
• dispersing the dielectric slurry including the recovered dielectric particles to the plurality of spraying modules.
