A dielectric powder includes a core-shell structure including a core region formed in an inner portion thereof and a shell region covering the core region. The core region includes barium titanate (BaTiO.sub.3) doped with a metal oxide, and the shell region is formed of a ferroelectric material.

A multilayer ceramic device includes a multilayer chip. The multilayer chip has a capacity section, a side margin and an intermediate portion. The intermediate portion is provided between the capacity section and the side margin. An A/B ratio is larger in the side margin than in the capacity section, and is smaller in the intermediate portion than in the capacity section.

A multilayer ceramic capacitor includes a ceramic body and first to fourth external electrodes. The ceramic body has first to fourth side surfaces, first to fourth ridges connecting the two side surfaces, and first and second internal electrodes. External electrodes cover the respective ridges and are connected to internal electrodes. The multilayer ceramic capacitor has a height dimension T of 110 m or less, and a ratio of a width dimension W to a length dimension L of 0.5 or more and less than 0.85. The internal electrodes extend obliquely outward relative to the X-axis and Y-axis directions from the facing portions, and have lead-out portions towards the ridges.

A method of manufacturing a dielectric slurry, includes supplying a dielectric slurry including dielectric particles and a solvent to a slurry supply module, dispersing the dielectric slurry by inserting the dielectric slurry into a particle dispersing module, classifying the dielectric particles according to particle size by inserting the dispersed dielectric slurry into a classifying module, recovering at least a portion of the dielectric particles to the slurry supply module, and redispersing the dielectric slurry including the dielectric particles recovered to the slurry supply module to the particle dispersing module.
