摘要：

Microcrystalline boron-doped diamond powders consisting of octahedrally faceted crystals have been synthesized in the C-H-B system at a pressure of 8 GPa and temperatures above 2000 K. The presence of boron has been shown to reduce the parameters of diamond synthesis compared to the binary system C-H (naphthalene). One possible reason for the reduction in synthesis parameters is the formation of less perfect graphite in the boron system in an intermediate step of diamond synthesis. At B/(C + B) ratios of about 5–10 at % in the C-H-B (naphthalene + boron) system, superconducting diamond microcrystals have been synthesized.
