Liquid-phase sintering and chemical inhomogeneity in the BaTiO3–BaCO3–LiF system

摘要: An ongoing goal of multilayer capacitor research is to lower the firing temperature dielectric. This paper gives a detailed study sintering BaTiO3 with LiF flux, which lowers through liquid-phase sintering. A set experiments discussed concerning microstructural evolution and corresponding dielectric properties under number processing variables, including amount LiF, temperature, particle size. Different scales chemical inhomogeneity were observed in this system, reflect two underlying mechanisms: solution reprecipitation limited grain growth at low temperatures, resulted distinct core–shell structures, flux volatility, gave rise microscopic higher temperatures.
