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 ε r ≈ 17.1, Q u f0 ≈ 195855 GHz, and τ f ≈ -46 ppm/°C. τ f was tuned through zero by mixing with Ca0.6La0.8/3TiO3. In the present study, τ f ≈ -2 ppm/°C with ε r ≈ 23.9 and high Q u f0 ≈ 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.
