Abstract

The behaviour of permittivity and loss tangent in the temperature range between 80 to 300 K of several alumina grades is presented. The data are obtained using a resonant cavity technique. The results show smaller temperature dependence for the polycristalline grades, in contrast with the observed behaviour of monocrystalline ones.
