ELECTRICALLY CONDUCTIVE POLYCRYSTALLINE SUPER HARD MATERIAL BASED ON DIAMOND AND n-LAYER GRAPHENES

The electrical and physical properties of the electrically conductive super hard mate-rial on the basis of polycrystalline diamond and n-layered graphenes obtained at high pres-sures and temperatures were studied. It was established that the increase in graphene in a polycrystalline diamond compact leads to a sharp decrease in resistance. Wherein the hard-ness of the samples is slightly inferior to the hardness of diamond poly crystals obtained without the use of graphene.

Key words: diamond, graphene, high pressure, poly crystal, conductivity
