A lead-free Ba(1-x)CaxTi(1-y)ZryO3 (BCZT) single crystal (x = 0.08, y = 0.26) was grown by the Czochralski (CZ) method in a mixed flux of TiO2 and ZrO2. The composition of as-grown BCZT was analyzed by electron probe micro-analysis. The structure, dielectric properties and phase transition were investigated at different temperatures. The X-ray diffraction results confirmed that the structure of the as-grown BCZT crystal was cubic both at 25 degrees C and 500 degrees C. The temperature dependence of the dielectric constant and Raman spectra characterization revealed that there was a phase transition from cubic to tetragonal, which happened between 200 K and 250 K. With increasing frequency, the Curie temperature shifted towards high temperature. (C) 2012 Elsevier BM. All rights reserved.
