摘要

Process for the fabrication of monocrystalline graphite, comprises: maintaining, in a crucible (5) made of a material comprising carbon, a metal bath (3) solvent for the carbon at a temperature such that this metal is liquid and is adapted to dissolve carbon from the crucible in pure form, where the bath is subjected to a vertical concentration gradient, and the concentration is higher on the surface.
