Microwave dielectric properties of Ca1-xSrxMgSi2O6 ceramics
Source abstract
Abstract
Abstract The influences of Sr2+ doping on microwave dielectric properties of Ca1-xSrxMgSi2O6 (x = 0–0.06) ceramics were researched in the work. The intrinsic mechanism responsible for the dielectric properties was explored by the P–V-L theory and Raman spectra. X-ray diffraction revealed that Ca1-xSrxMgSi2O6 solid solutions were formed when x = 0.02–0.06. The er continually increased with an increasing x value, which was related to the average bond ionicity and dielectric polarizability. The change of Qf was due to the variation in Si–O bond. The τf was affected by the Ca/Sr–O bond energy. Furthermore, the Ca0·96Sr0·04MgSi2O6 ceramic sintered at 1320 °C possessed optimum dielectric properties (er = 8.17, Qf = 85858 GHz, and τf = −41.25 ppm/°C).
