Dielectric Characteristics of Doped Strontium Titanate within Broad Temperature Range

Abstract:

Article Preview

Dielectric characteristics of strontium titanate based ceramics doped with samarium were investigated within temperature range from –60oC to 150oC. 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.
