Resumo

The results of the synthesis and analysis of diamond crystals with heavy boron doping (about 2%), which were obtained from mixtures of gas black with m-carborane at 8 GPa and 1873 K, are presented. A high boron concentration in the diamond lattice was confirmed by x-ray data and the characteristic Raman scattering spectra, which correspond to diamond with metallic conductivity. Thermobaric treatment of the diamond-like dl-BC3 phase (1100 K, 25 GPa) results in the formation of BC3-heteronanodiamond.
