Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. 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 (BaTiO 3 ) 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. 2. The multilayer ceramic electronic component of claim 1 , wherein the first shell portion is disposed on the surface of the core portion and the second shell portion is disposed on a surface of the first shell portion. 3. The multilayer ceramic electronic component of claim 1 , wherein the first additive includes one or more of Dy, Y, V, Mg, Mn, Ba, Si, Al, Cr, or Ca. 4. The multilayer ceramic electronic component of claim 1 , wherein the shell portion further includes at least a third shell portion. 5. The multilayer ceramic electronic component of claim 1 , wherein the first shell portion is disposed on the surface of the core portion and the second shell portion is disposed on a surface of the first shell portion, and wherein the shell portion further includes at least a third shell portion disposed on a surface of the second shell portion. 6. The multilayer ceramic electronic component of claim 1 , wherein the shell portion further includes at least a third shell portion disposed on a surface of the second shell portion, wherein the third shell portion includes the second additive, and the concentration of the second additive is highest in the second shell portion.
