New dielectric material system of x(Mg0.95Zn0.05Ti)O3–(1−x)Ca0.8Sm0.4/3TiO3 at microwave frequency

Sintering behavior and microwave dielectric properties of Y2O3–ZnO doped (Zr0.8Sn0.2)TiO4 ceramics

“…The optimal Q 9 f value of 48,545 GHz (at 5.5 GHz) is obtained for 1 wt% ZnO doped ZST ceramics with 0.5 wt% Y 2 O 3 addition at 1240°C. The microwave dielectric loss includes not only intrinsic losses mainly caused by the lattice vibration modes but also extrinsic losses dominated by densification/porosity, the secondary phases, grain sizes and oxygen vacancies [17,18]. Among these factors, the abnormal grain growth and the degradation of densities are suggested to affect the Q 9 f values obviously with the further more additives.…”

Study of (1−x)(Mg0.6Zn0.4)0.95Co0.05TiO3–xCa0.61Nd0.26TiO3 microwave dielectrics

“…Huang et al reported that a new series of microwave dielectric materials with positive temperature coefficient of resonant frequency were added to (Mg, Co, Zn)TiO 3 ceramic system. The experiment results showed that these ceramic systems had excellent microwave dielectric properties [9][10][11][12].…”

New dielectric material system of Nd(Mg1/2Ti1/2)O3–CaTiO3 with V2O5 addition for microwave applications

“…Targeting at compensating their temperature coefficient of resonant frequency values, an effective method has been developed to combine two or more compounds with negative and positive temperature coefficients, respectively, to form solid solutions or mixed phases [1][2][3]. Although most dielectric ceramics with high dielectric constants have positive f values, materials with a high dielectric constant, high Q and negative f are desired to achieve this goal.…”
