In this paper the authors study the effect of annealing on the spectra of normal IR reflection of polycrystalline specimens of cubic boron nitride obtained by sintering 50- to 200- US -BN crystals at pressures and temperatures corresponding to the region of thermodynamic stability of US -BN. These crystals were synthesized from a mixture of graphite-like boron nitride with magnesium diboride and contained impurities (mass%): 0.1 silicon, 0.15 calcium, 0.8 magnesium, 0.13 aluminum and 0.3 iron. Polished sections of the specimens were prepared with diamond disks of different grain sizes. The specular surface on which the reflectivity was measured was parallel to the vertical axis of the specimen, and its area was equal to 20 mmS.
