Abstract
A method of producing a core-shell particle includes introducing a barium titanate-based base powder and an additive to a reactor, and exposing the barium titanate-based base powder and the additive to a thermal plasma torch to obtain core-shell particles including a core portion having barium titanate (BaTiO3) and a shell portion including the additive and formed on a surface of the core portion.
Claims6
A multilayer ceramic electronic component comprising:
- a ceramic body including a dielectric layer;
- and
- internal electrode layers disposed to face each other with the dielectric layer interposed therebetween in the ceramic body,
- wherein the dielectric layer includes a core-shell dielectric grain including a core portion having barium titanate (BaTiO3) and a shell portion disposed on a surface of the core portion, and the core-shell dielectric grain is a core-multishell dielectric grain in which the shell portion includes a first shell portion and a second shell portion,
- wherein the first and second shell portions each include a first additive and a second additive, and
- wherein a concentration of the first additive in the first shell portion is higher than in the second shell portion and a concentration of the second additive in the second shell portion is higher than in the first shell portion.
