Abstract

All the compositions in the (1−x)Mg0.95Ni0.05Ti0.98Zr0.02O3–xCa0.6La0.8/3TiO3 (0 ≤ x ≤ 0.2) series were fabricated using solid state sintering route. Mg0.95Ni0.05Ti0.98Zr0.02O3 possessed excellent microwave dielectric properties with εr ≈ 17.1, Quf0 ≈ 195855 GHz, and τf ≈ -46 ppm/℃. τf was tuned through zero by mixing with Ca0.6La0.8/3TiO3. In the present study, τf ≈ -2 ppm/℃ with εr ≈ 23.9 and high Quf0 ≈ 115870 GHz was achieved for x = 0.15, i.e., for a mixture of 85% Mg0.95Ni0.05Ti0.98Zr0.02O3 and 15% Ca0.6La0.8/3TiO3.
