Abstract:

Low-temperature sintered Ca₂Zn₄Ti₁₅O₃₆ microwave dielectric ceramic was prepared by conventional solid state reaction method. The influences from V₂O₅ addition on the sintering behavior, crystalline phases, microstructures and microwave dielectric properties were investigated. The crystalline phases and microstructures of Ca₂Zn₄Ti₁₅O₃₆ ceramic with V₂O₅ addition were investigated by X-ray diffraction, scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). V₂O₅ addition lowered the sintering temperature of Ca₂Zn₄Ti₁₅O₃₆ ceramics from 1140 °C to 930 °C. Ca₂Zn₄Ti₁₅O₃₆ ceramic with 5wt% V₂O₅ addition could be densified well at 930 °C, and showed good microwave dielectric properties of ε_r ~ 46, Q × f ~ 13400 GHz, and temperature coefficient of resonant frequency (τ_f) ~ 164 ppm/°C.
