摘要: Abstract Experimental data are presented on the changes of thermal conductivity a number polycrystalline graphites due to doping with boron and bromine, which respectively represent substitutional interstitial acceptor type defect. The results compared in atoms vacancies introduced by fast neutron irradiation. It is found that atom its ability scatter phonons roughly comparable lattice vacancy. temperature dependence additional resistance all four types defects be similarly increasing decreasing temperature. A detailed attempt fit theoretical curve indicates mean free path for phonon scattering point independent frequency.
