# High-Q Microwave Dielectric SrTiO3-Doped MgTiO3 Materials with Near-Zero Temperature Coefficient of Resonant Frequency

## 抄録

The microwave dielectric properties of the ($1-x$)MgTiO3–$x$SrTiO3 system have been investigated. The objective of the present work is to compensate for the negative temperature coefficient of the resonant frequency ($\tau_{\text{f}}$) of MgTiO3 by addition of SrTiO3. The variation in microwave properties of the system significantly depends on the amount of SrTiO3 present, and they can be matched using mixing rules. With increasing $x$, the dielectric constant ($\varepsilon_{\text{r}}$) increased and the quality factor ($Qf$) decreased. A ceramic sample with $x=0.036$ of SrTiO3, sintered at 1270°C for 2 h, and having a near-zero temperature coefficient of resonant frequency ($\tau_{\text{f}}$) of $-1.3$ ppm/°C can be obtained.
