摘要：

The effect of Ca0.61Nd0.26TiO3 addition on the microwave dielectric properties of (Mg0.95Ni0.05)TiO3 ceramics was investigated. The Ca0.61Nd0.26TiO3 Content plays a significant role in improving the dielectric properties. Microwave dielectric measurements show an increase in the dielectric constant (epsilon(r)) and temperature coefficient of the resonant frequency (tau(f)) and a decrease in the quality factor (Q x f value) with increasing Ca0.61Nd0.26TiO3 content. By properly adjusting the Ca0.61Nd0.26TiO3 content, a zero temperature coefficient of resonate frequency (tau(f)) can also be obtained, which make (Mg0.95Ni0.05)TiO3 a promising material in wireless systems. At 1350 degrees C, the 0.85(Mg0.95Ni0.05)TiO3-0.15Ca(0.61)Nd(0.26)TiO(3) ceramics possess excellent microwave dielectric properties: a dielectric constant (epsilon(r)) of 24.05, a Q x f value of 67,000 GHz, and a tau(f) value of -9.3 ppm/degrees C.
