METHOD AND APPARATUS FOR PRODUCING GRANULAR SILICON

Silicon granules are produced by chemical vapor deposition on seed particles inside a chamber within a fluidized bed reactor. The chamber contains an obstructing member, or bubble breaker, which is sized and shaped to restrict the growth of bubbles inside the chamber and which has interior passagewa...

More Information
Summary:Silicon granules are produced by chemical vapor deposition on seed particles inside a chamber within a fluidized bed reactor. The chamber contains an obstructing member, or bubble breaker, which is sized and shaped to restrict the growth of bubbles inside the chamber and which has interior passageways through which a heated fluid passes to transfer heat to gas inside the chamber. L'invention concerne des granulés de silicium, qui sont produits par dépôt chimique en phase vapeur sur des particules germes dans une chambre dans un réacteur à lit fluidisé. La chambre contient un élément d'obstruction, ou pulvérisateur anti-mousse, qui est dimensionné et formé pour restreindre la croissance de bulles dans la chambre et qui contient des passages intérieurs dans lesquels un fluide chauffé passe pour transférer de la chaleur au gaz contenu dans la chambre.
