Abstract
In this chapter we give examples of the behavior of heat capacity and thermal expansion for some of the important classes of non-metallic solids, in which itinerant electrons make little or no contribution. Usually the dominant contributions to the heat capacity and thermal expansion are those of the lattice vibrations. At very low temperatures these can be related to the elasticity, and as the temperature increases to the phonon frequencies as determined by neutron diffraction (Section 2.6.2). But some of the solids also display non-vibrational effects, due for example to localized magnetic moments, or to quantum tunnelling of atoms between different sites.
