The problem of computing the lattice thermal conductivity and the phonon‐drag contribution to the electrical resistivity in presence of normal phonon–phonon processes is examined in the framework of the Boltzmann‐Callaway equation. A previous treatment for the lattice thermal conductivity of insulating crystals by Callaway and Krumhansl is appropriately extended in order to treat the properties of interest. The so‐obtained expressions for the lattice thermal conductivity and the phonon‐drag contribution are presented. Some inconsistences of recent works on the same arguments are discussed in reference to the results obtained.
