(Co1-xZnx)TiO3 (x = 0-0.1) ceramics with high relative density were prepared by the conventional solid-state reaction, followed by sintering at 1290-1380 °C. X-ray diffraction patterns illustrated that a single rhombohedral crystal structure solid solution could be formed between the two end members with 0 ≤ x ≤ 0.1. The unit cell volume slightly increased with increasing Zn content (x). The microwave dielectric properties of (Co1-xZnx)TiO3 ceramics showed a significant dependence on the Zn content, the density of the specimen, and to some extent on the morphology of the grains. Specimen using (Co 0.95Zn0.05)TiO3 sintered at 1350 °C for 3 h could obtain the microwave dielectric properties as follows; an r value of ∼20, a Q × f value of ∼107,000 GHz (measured at f = 9.27 GHz), and a τf value of -60 ppm/°C.
