Permittivity of Alumina >95%?

  1. Jun 29, 2012 #1

    I was wondering if anyone could tell me the permittivity of Al2O3 >95% polished, or how to calculate it? Any useful electrical properties websites or books would be much appreciated.

    Also I was wondering if the the permittivity was frequency dependent?

    Thanks in advance
