Query: Superdielectric Materials Composed of Sodium Chloride, Water and Porous
  Alumina   Superdielectric behavior was observed in pastes made of high surface area
alumina filled to the level of incipient wetness with water containing
dissolved sodium chloride (table salt). In some cases the dielectric constants
were greater than 10^10.
