Structure characteristics and microwave dielectric properties of Pr2(Zr1-xTix)3(MoO4)9 solid solution ceramic with a stable temperature coefficient
文献摘要：
Pr2(Zr1-xTix)3(MoO4)9(x=0.1-1.0)ceramics were prepared via a conventional solid-state method,the dependence of crystal structure and bond characteristics on microwave dielectric properties was investi-gated systemically.The X-ray diffraction patterns indicated that the single-phase Pr2Zr3(MoO4)9 structure was formed in all the specimens.As the Ti4+content increased,the lattice volume gradually decreased,which was ascribed to the fact that the ionic radius of Ti4+was smaller than that of Zr4+.Notably,out-standing microwave dielectric properties with εr of 10.73-16.35,Qf values of 80,696-18,726 GHz and minor rf values-14.1--2.6 ppm/℃were achieved in Pr2(Zr1-xTix)3(MoO4)9 ceramics.The εr increased with the rising x values,which was associated with the increase of α/Vm values.The decreasing Qf was affected by the decline of lattice energy of[Zr/TiO6]octahedral.The τf value was dominated by[Zr/TiO6]octahedral distortion,Mo-O bond energy,bond strength and B-site bond valence.Furthermore,infrared reflection spectra suggested that the properties were mainly caused by the absorption of phonon,and the dielectric loss could be further reduced by optimizing the experimental process.
