This investigation deals with the influence of selenium impurity and thermal annealing on the properties of beta-BN. It is shown that as a result of annealing of cubic boron nitride, undoped or doped with selenium, both electrical and thermal conductivity are increased, depending also on the defects in the beta-BN crystals. The concentration of selenium in boron nitride was obtained by x-ray luminescence methods. To excite the x-ray radiation of selenium, a Cd 109 radioisotope source was used with an integrated activity of approximately 1 MBq.
