Device (20) for purifying a molten material such as silicon, comprising a chamber (21) comprising a crucible (2; 15) for storing a molten material and a heating device (4) for heating the molten material contained in the crucible, the chamber being equipped with a device (22) for greatly lowering the pressure in the chamber, characterized in that it comprises at least one evaporator (10; 10, 10′) placed inside the chamber to receive part of the molten material, such that this molten material has a large interface with low-pressure vapour present in the chamber (21) to promote and accelerate the purification of the molten material. |
