Abstract

Abstract: The liquid mixing method by using ethylenediaminetetraacetic acid as a chelating agent to prepare Ba₂Ti₉O₂₀ was reported. The resin precursors were prepared and heated at 700℃ to 1200℃ in air. XRD was used to determine the phase transformations as a function of temperature. Single-phase Ba₂Ti₉O₂₀ was obtained at l200℃, without the prolonged heat treatment time. DTA, TG and Raman spectra were used to characterize the precursors and derived oxide powders, respectively

Key words: Ba₂Ti₉O₂₀, EDTA, synthesis, liquid mixing method
