Thermal Conduction in Mica along the Planes of Cleavage

Abstract

A NUMBER of measurements on the thermal conductivity of mica perpendicular to the cleavage planes have been carried out in the past1,2. However, apart from the work of Jannetaz3, which suggests that the thermal conductivity is highly anisotropic, no data appear to be available relating to conduction along the planes. We report here the results of some measurements, with heat flow along the planes of cleavage, on phlogopite, a type of mica which is effectively uniaxial and isotropic within the layers.
