In crystalline materials, thermal conductivity is a function of the direction that heat flows, directly analogous to the refractive index. In gen- eral, the thermal and optical symmetry will be the same (Washburn, 1929, p. 230). Thus, non- isometric gems will have a conductivity depen- dent on the direction of heat flow during testing.

Thermal Conductivity - Definition and Detailed Explanation

Effect on Thermal Conductivity: The chemical phase of the material: When the phase of a material changes, an abrupt change in its heat conductivity may arise. For example, the thermal conductivity of ice changes from 2.18 Wm-1 K-1 to 0.56 Wm-1 K-1 when it melts into a liquid phase: Thermal Anisotropy
