Dielectric Properties of MgAl2O4 Transparent Nano-Ceramic

Dielectric constant and dielectric dissipation of MgAl2O4 transparent nano-ceramics were measured at different frequencies. The results indicated that the transparent nano-ceramic has a very low dielectric constant and low dielectric dissipation in frequency range of 1K~9MHz, but the dissipation of is independent of frequency. The dielectric constant of the transparent nano-ceramic does not vary signifycantly with temperature.
