Abstract

Monoclinic-structure ZnZrNb2O8 were firstly prepared by reaction sintering process based on conventional solid state method. Sintering characteristics and microwave dielectric properties of ZnZrNb2O8 ceramics were investigated depending on sintering temperatures ranging from 1100 to 1300 °C. Both xrd patterns and scanning electronic microscopes were used for the characterization of phase evaluation and microstructure. The dielectric properties were strongly dependent on the compositions, the densifications and the microstructures of the specimens. Compared with the conventional solid state process, the specimens with nearly full density could be obtained at a lower sintering temperature of 1200 °C with excellent microwave properties with an ɛ r of 28.37, an high Q·f of 63,300 GHz, and a τ f of −19.9 ppm/ °C.
