THE THERMAL CONDUCTIVITY OF CERAMIC DIELECTRICS
Technical Report

OSTI ID:4000449
The thermal conductivity of dielectric solids at various temperatures is discussed in terms of the mean-free path concept snd its application to phonon- and photon-energy transfer. In single crystals and glasses, the effects of temperature, composition, structure, boundary conditions, impurities, solid solutions, and neutron irradiation are discussed. From these considerations the resultant conductivity is derived in terms of phase composition and microstructure. It is concluded that conduction processes are well understood, and thnt the conductivity of complex ceramics can be predicted if the chemical and physical composition are adequately described. (auth)
