| 中文摘要 | Dielectric characteristics of strontium titanate based ceramics doped with samarium were investigated within temperature range from -60 degrees C to 150 degrees C. XRD was used to identify the phase compositions of the ceramics and the microstructures were characterized by SEM. Good temperature coefficient of capacitance (TCC) was observed: TCC = +18%--11% with high dielectric constant of 18000 and relative low dielectric loss. After further modification, the present ceramics might be promising candidates for the multilayer ceramic capacitors applications at high temperature. |
