DIELECTRIC PROPERTIES OF Ca(1-z)ZnzLa4TisO17 CERAMICS AT MICROWAVE FREQUENCIES

摘要：

In this paper, the microwave dielectric properties of Ca(1-x)ZnxLa4Ti5O17 ceramics have been studied. The diffraction peaks of Ca(1-x)ZnxLa4Ti5O17 ceramics shift to higher angles as x increases from 0 to 0.01 and nearly unchanged with x increasing from 0.01 to 0.03. A maximum density of dielectric constant value of 57 and a quality factor (Q × f) of 15000 GHz can be obtained for Ca0.99Zn0.01La4Ti5O17 ceramic sintered at 1450℃ for 4h. A near-zero temperature coefficient of resonant frequency (τf) of -8.1 ppm/℃ can be obtained for Ca0.99Zn0.01La4Ti5O17 ceramic sintered at 1450℃ for 4h.
