Composition-Microstructure-Property Relationships in BaTiO₃ with Mg Addition

Abstract

Rising worldwide demands for energy encourages development of high-efficiency energy storage and capacitor components. Main requirements for dielectric materials employed in fabrication of high energy density capacitors include high dielectric constant, high dielectric breakdown strength, and low dielectric loss. Owing to its high dielectric constant and low dielectric loss [1], barium titanate is among common capacitor materials. Tailoring of dielectric properties of barium titanate can be achieved through controlled chemical composition, microstructure, and crystal structure. Synthesis and processing techniques, as well as doping of barium titanate, can be key factors to control the composition and structure, which consequently contribute to enhancement of dielectric constant in the material.

“…01-071-2394), whose formation can be associated with a chemical reaction between barium from the initial reagent and carbon from CO 2 or the combustion fuel. Khort et al reported the formation of BaCO 3 via the reaction between barium oxide (decomposed from barium nitrate) and CO 2 , whereas Jongprateep and Tanmee observed the formation of BaCO 3 via the reaction between barium oxide and carbon from glycine [27,41].…”
