摘要：
The microwave dielectric properties of (1−x)Mg(Zr0.05Ti0.95)O3-xSrTiO3 ceramics prepared by conventional solid processing were investigated. With increasing x, the dielectric constant and the quality factor decreased, and the temperature coefficient of resonant frequency was tuned from negative to positive value. The effect of sintering temperature on microwave properties was also studied. After sintering at 1,390 °C for 4 h, the ceramics exhibited a near zero temperature coefficient of resonant frequency about 2.1 ppm/°C, an optimum dielectric constant of 20.9 and a high quality factor of 203000 (6.8 GHz), at the level of x = 0.05.
