Electrical Properties of Yttrium-Aluminum-Silicon Oxynitride Glasses
The ac electrical properties of several Y‐Al‐Si oxynitride glasses were measured as a function of temperature at 20° to 625°C in the frequency range 50 to 105 Hz. The low‐field dc conductivity was also determined. Dispersions in the dielectric constant associated with the peaks in the tan δ curves w...

| Zusammenfassung: | The ac electrical properties of several Y‐Al‐Si oxynitride glasses were measured as a function of temperature at 20° to 625°C in the frequency range 50 to 105 Hz. The low‐field dc conductivity was also determined. Dispersions in the dielectric constant associated with the peaks in the tan δ curves were observed in all cases. The peaks in tan δ shifted to higher frequencies with increasing temperature. Below ∼400°C, the ac conductivity was proportional to ωn with 0.5 |
