Abstract: A multilayer capacitor includes a capacitor body including dielectric layers and internal electrodes alternately disposed with the dielectric layers interposed therebetween; and an external electrode disposed on the capacitor body to be connected to one or more of the internal electrodes. Porosity of ends of the internal electrodes is less than 50% on an interfacial surface between a margin of the capacitor body in a width direction the capacitor body and the internal electrodes.

Abstract: A whitlockite preparation method includes: determining a size of the whitlockite crystal to be prepared; determining a first amount of a first cation other than calcium ion on the basis of the determined size of the crystal, wherein when the determined size of the whitlockite crystal is a first size, the first amount is determined to be a first value, wherein when the determined size is a second size larger than the first size, the first amount is determined to be a second value; mixing calcium ion and phosphate ion in order to prepare a first phosphate crystal, wherein the determined first amount of the cation other than calcium ion is also mixed therewith; mixing a second amount of cation other than calcium ion with phosphate ion to prepare a second phosphate crystal; and aging a solution containing the first phosphate crystal and the second phosphate crystal.
