An electrically conductive boron-doped diamond material with high thermal stability and good mechanical properties has been synthesized at high pressures from powder mixtures of graphite and boron carbide. Specific microstructure and high elastic moduli of samples obtained indicate the formation of polycrystalline diamond matrix in the material. The unique combination of physicochemical properties offered by heavily boron-doped diamond can extend its application area as an electrostructural material capable of operating in aggressive media.
