摘要：
Co0.5Sn0.5TaO4 ceramic was fabricated in this study, where the structural configuration and dielectric properties were discussed. A trirutile-type was confirmed via X-ray diffraction, Raman scatting spectroscopy, and TEM analysis. Temperature-stable Co0.5Sn0.5TaO4 ceramic with excellent microwave dielectric properties of an epsilon r value -18.6, a Q x f value about 36875 GHz (10.3 GHz) was achieved under TE011 mode; moreover, a tan delta value as low as -8 x 10-3 was also identified at 0.6 THz, showing prospects in high-frequency applications.
