Thermal conductivity in insulators,

Thermal conductivity in insulators, ceramics and
polymers is mainly attributed to the phonon component. The solid is imagined to contain a phonon gas
similar to the electron gas in a metal. At the hot end
of a solid the kinetic energy of the phonons is
greater than at the cold end. This energy is gradually
transferred from hot to cold by phonon–phonon
interactions and by interactions between the phonons and the solid structure.
