The determination of the Debye temperature for a material is thought to include some ambiguity, since the Debye temperature is dependent on temperature and the method of the measurement. At the limit to O K, however, the Debye approximation of an elastic continuum becomes valid for real crystals and the Debye temperatures obtained from the low temperature heat capacity, the elastic constant and the neutron inelastic scattering become in good agreement. Various methods to determine the Debye temperature, and the temperature and composition dependences of the Debye temperature have been reviewed. Correlations between the Debye temperature and physical properties of materials such as isothermal compressibility, melting point, diffusion constant, thermal expansion coefficient and heat of formation have been discussed using the data of various materials.
