          Abstract

          All the compositions in the (1− x)Mg 0.95Ni 0.05Ti 0.98Zr 0.02O 3xCa 0.6La 0.8/3TiO 3 (0 ≤ x ≤ 0.2) series were fabricated using solid state sintering route. Mg 0.95Ni 0.05Ti 0.98Zr 0.02O 3 possessed excellent microwave dielectric properties with ε r ≈ 17.1, Q u f 0 ≈ 195855 GHz, and τ f ≈ -46 ppm/℃. τ f was tuned through zero by mixing with Ca 0.6La 0.8/3TiO 3. In the present study, τ f ≈ -2 ppm/℃ with ε r ≈ 23.9 and high Q u f 0 ≈ 115870 GHz was achieved for x = 0.15, i.e., for a mixture of 85% Mg 0.95Ni 0.05Ti 0.98Zr 0.02O 3 and 15% Ca 0.6La 0.8/3TiO 3.
