Abstract (en)
[origin: WO2019234072A1] The invention relates to a device (10) for producing molten silicon (11), comprising an enclosure (12) and comprising, in the enclosure: a crucible (15) intended to receive powder (19) of oxidised particles of silicon, the crucible comprising an internal volume (16) intended to contain silicon in the molten state and silica and a channel (28) for discharging silicon in the molten state out of the internal volume, the crucible comprising at least two holes (32), the straight section of each hole having a maximum dimension that is greater than or equal to a value between 1 mm and 10 mm, or at least one slot, the straight section of which has a maximum dimension that is greater than or equal to a value between 1 mm and 10 mm connecting the internal volume to the crucible; and a heating system (20) at least partly surrounding the crucible.
