چکیده انگلیسی
This work presents the microwave dielectric properties of TiO2 incorporated Zn2TiO4 sintered at low-temperatures. The Zn2TiO4 was synthesized using ZnO and TiO2 nanowires as starting materials. Within the interim studied (TiO2 = 0-12%), the bulk density, the dielectric constant, and the quality factor markedly increased with sintering temperature. When the TiO2 content (x) was 8% (970 °C), the value of quality factor multiples its resonant frequency of the Zn2TiO4:8% TiO2 achieved a maximum of â¼35,000 GHz. From XRD patterns, the phase stability of TiO2 added Zn2TiO4 changed when the TiO2 content exceeded 10 wt%. Further addition of TiO2 up to 12% approached zero, with high quality factor and k values of 30,000 GHz and 22, respectively. The high quality factor was attributed to the good cyrstallinity of Zn2TiO4. The fabricated Zn2TiO4:12% TiO2 ceramic is suitable for microwave dielectric applications.
