Abstract (en)

[origin: FR2912397A1] Installation for refining silicon comprises a crucible with a base made of a refractory material with high thermal conductivity, a device for cooling the base, a protective shield of refractory material with low thermal conductivity disposed between the crucible and the silicon charge, and an induction coil disposed in or beneath the base for heating the charge. An independent claim is also included for refining a silicon charge in an installation as above by placing the charge on the protective shield, cooling the base and heating the charge with the induction coil.
