چکیده انگلیسی
The microstructures and microwave dielectric characteristics of complex perovskite Nd(Co1/2Ti1/2)O3 ceramics with 60P2O5–15ZnO–5La2O3–5Al2O3–5Na2O–5MgO–5Yb2O3 (PZLANMY) additions (1–4 wt%) prepared through the conventional solid-state route were investigated. It was found that Nd(Co1/2Ti1/2)O3 ceramics can be sintered at 1210 °C owing to the sintering aid of PZLANMY-glass addition. At 1300 °C, Nd(Co1/2Ti1/2)O3 ceramics with 1 wt% of PZLANMY-glass addition possess a dielectric constant (εr) of 27, a Q×f value of 64,000 GHz and a temperature coefficient of resonant frequency (τf) of −29 ppm/°C. The PZLANMY-glass doped Nd(Co1/2Ti1/2)O3 ceramics can find applications in microwave devices that require low sintering temperature.
