CA 2746041

A method for producing silicon, the method comprising a heating step of heating a metal powder M p1 made of at least one member selected from the group consisting of Mg, Ca and A l in a plasma P; and a reducing step of reducing a halogenated silane G1 by the metal powder M P2 heated in the plasma P to obtain silicon.

L'invention concerne un procédé de fabrication de silicium qui met en uvre une étape de chauffage consistant à chauffer, dans un plasma P une poudre métallique (MP1) comprenant au moins une sorte de métal choisie parmi un groupe composé de Mg, Ca et Al; et une étape de réduction qui réduit, à l'aide d'une poudre métallique (MP2) chauffée dans un plasma (P), un silane halogéné (G1) et qui permet d'obtenir du silicium.
