- Abstract
Lead-free (1− x)BaCaTiO- xBi(MgZr)O [(1− x)BCT- xBMZ, 0 ≤ x ≤ 0.3] ceramics were fabricated via a conventional solid-state reaction method. The structure and dielectric properties of BCT-BMZ ceramics were systematically investigated. X-ray diffraction patterns and Raman spectra show that a systematically structural change form a tetragonal to pseudo-cubic phase occurred at about x = 0.06-0.08. As x values increased to 0.3, the temperature stability of permittivity of ceramics was markedly increased (Δ ε/ ε ≤ ±15 %) and low dielectric loss (≤2 %) was obtained over a wide temperature range from 27 to 290 °C at 1 kHz. These results indicate that (1− x)BCT- xBMZ ceramics are promising candidates for thermally stabile devices.
