Abstract

Low-temperature sintered Ca 2Zn 4Ti 15 O 36 microwave dielectric ceramic was prepared by conventional solid state reaction method. The influences from V 2 O 5 addition on the sintering behavior, crystalline phases, microstructures and microwave dielectric properties were investigated. The crystalline phases and microstructures of Ca 2 Zn 4Ti 15O 36 ceramic with V 2 O 5 addition were investigated by X-ray diffraction, scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). V 2O 5 addition lowered the sintering temperature of Ca 2Zn 4Ti 15O 36 ceramics from 1140 °C to 930 °C. Ca 2Zn 4 Ti 15O 36 ceramic with 5wt% V 2 O 5 addition could be densified well at 930°C, and showed good microwave dielectric properties of ετ r∼ 46, Q × f ∼ 13400 GHz, and temperature coefficient of resonant frequency (τ f)∼164 ppm/°C.
