(1-x)BaTiO3-xBi(Li1/3Zr2/3)O3 [(1-x)BT-xBLZ, 0.02 ≤ x ≤ 0.1] solid solution ceramics were prepared by a conventional solid state reaction technique. The effects of BLZ addition on the phase structure and dielectric properties of ceramics were systematically studied. Raman spectra and XRD analysis confirmed that the ceramics transform from tetragonal to pseudocubic symmetry at 0.04 ≤ x ≤ 0.06. High thermal stability of permittivity and low dielectric loss were obtained with increasing BLZ contents. When x = 0.1, the ceramics possessed optimum dielectric performance with good thermal stability of permittivity (Δε/ε25°C ≤ ±15%) over a broad temperature range from −70 °C to 144 °C and low dielectric loss (≤ 2%) from −21 °C to 200 °C, suggesting that (1-x)BT-xBLZ ceramics are promising candidates for thermally stable electronic components.
