    • Abstract


      Microwave dielectric ceramics in Sr1-𝑥Ca𝑥La4Ti4.93Zr0.07O17 (0 ≤ 𝑥 ≤ 0.5) composition series were processed via a solid-state sintering rout. X-ray diffraction revealed single phase ceramics. Ca substitutions for Sr tuned 𝜏f towards zero with increased 𝑄u𝑓o values. In the present study, 𝜖r∼ 55, 𝑄u𝑓o ∼ 11960 GHz and 𝜏𝑓∼ 5.2 ppm/°C were achieved for the composition with 𝑥 = 0.3.
