Abstract

The invention provides a method of producing a core-shell particle and a multi-layer ceramic electronic component. The 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 a core-shell particle including a core portion having barium titanate (BaTiO3) and a shell portion including the additive and formed on a surface of the core portion.

Description

[0001] This application claims the benefit of priority of Korean Patent Application No. 10-2019-0154377 filed with the Korean Intellectual Property Office on November 27, 2019, the entire disclosure of which is hereby incorporated by reference for all purposes . technical field [0002] The present disclosure relates to a method of producing core-shell particles and multilayer ceramic electronic components including core-shell particles. Background technique [0003] With the rapid development of multifunctional, lightweight and miniaturized electronic products, the demand for small and high-performance electronic components continues to increase, and the need for high-reliability electronic components (compared with electronic Corresponding to the industry) demand has also increased significantly. [0004] Accordingly, competition for technological development of passive components such as inductors, capacitors, and resistors to meet market demands is accelerating. In det...
