Ilmenite‐type (Zn 1− x Cd x )TiO 3 (0≤ x ≤0.15 and 0.8≤ x ≤1.0) was synthesized by a modified sol–gel route including the Pechini process via two‐step heat treatments. The thermal stability of (Zn 1− x Cd x )TiO 3 depended on the amount of cadmium content. The as‐synthesized (Zn 1− x Cd x )TiO 3 (0≤ x ≤0.15 and 0.8≤ x ≤1.0) showed higher thermal stability than that of ZnTiO 3 . The variation of the dielectric constant of all synthesized (Zn 1− x Cd x )TiO 3 samples for all measurement frequencies showed a similar tendency. The dielectric constant of each (Zn 1− x Cd x )TiO 3 sample decreased first with increasing frequencies and then increased slightly when the frequency was up to 10 7 Hz. Moreover, the dielectric loss tangent of all synthesized (Zn 1− x Cd x )TiO 3 samples for all measurement frequencies also changed in similar patterns. The dielectric loss tangent decreased with increasing measurement frequencies. The microwave dielectric properties of (Zn 1− x Cd x )TiO 3 were changed with the cadmium doping content in the range of microwave frequency.
