FIELD: chemistry.
SUBSTANCE: mixture from source of carbon - graphite and metal-solvent based on nickel-manganese alloy in ratio 40:60 of weight respectively is prepared. 3.73-33.55 wt % of manganese carbide powder Mn7C3 and 2.27-20.45 wt % of nickel powder are introduced into mixture on condition that ratio of nickel and manganese in metal-solvent is preserved. Obtained charge is pressed into tablets, put into alundum crucible and thermally processed in vacuum.
EFFECT: increase of diamond crystals output and increase of grainularity part without using expensive inoculating diamond crystals.
