【摘要】 通过陶瓷烧结工艺研究了Ba_0.6Sr_0.4(Zr_0.2Sn_xTi_0.8-x)O₃材料。性能测试结果表明,该固溶体是一种优异的可调材料,当x=0.03时,在1.5 k V/mm电场下,介电常数低于2000,可调性达到27.9%,介电损耗低至0.00010（100k Hz,室温）。XRD结果显示该固溶体是典型的钙钛矿结构。更多还原

【Abstract】 Ba_0.6Sr_0.4(Zr_0.2Sn_xTi_{0.8- x})O₃ ceramics were obtained by ceramic sintering processing. The results show that Ba_0.6Sr_0.4(Zr_0.2Sn_xTi_{0.8- x})O₃ ceramic is a promising candidate for the DC electric field tunable materials,because they exhibit high relative dielectric tunability 27. 9%（ x = 0. 03） at 1. 5 k V /mm,low dielectric constant < 2000（ when x > 0. 01）,and very low dielectric loss 0. 00010（ x = 0. 05）at 100 k Hz and room temperature. X-ray diffraction analyses indicates that the samples present perovskite phase.更多还原
