Abstract

Ilmenite‐type (Zn1−xCdx)TiO3 (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 (Zn1−xCdx)TiO3 depended on the amount of cadmium content. The as‐synthesized (Zn1−xCdx)TiO3 (0≤x≤0.15 and 0.8≤x≤1.0) showed higher thermal stability than that of ZnTiO3. The variation of the dielectric constant of all synthesized (Zn1−xCdx)TiO3 samples for all measurement frequencies showed a similar tendency. The dielectric constant of each (Zn1−xCdx)TiO3 sample decreased first with increasing frequencies and then increased slightly when the frequency was up to 107 Hz. Moreover, the dielectric loss tangent of all synthesized (Zn1−xCdx)TiO3 samples for all measurement frequencies also changed in similar patterns. The dielectric loss tangent decreased with increasing measurement frequencies. The microwave dielectric properties of (Zn1−xCdx)TiO3 were changed with the cadmium doping content in the range of microwave frequency.
