Mechanically fluidized systems and processes allow for efficient, cost-effective production of silicon. Particulate may be provided to a heated tray or pan, which is oscillated or vibrated to provide a reaction surface. The particulate migrates downward in the tray or pan and the reactant product migrates upward in the tray or pan as the reactant product reaches a desired state. Exhausted gases may be recycled. Systèmes fluidisés mécaniquement et procédés permettant une production de silicium efficace et rentable. On peut amener des particules à un plateau ou bac chauffé, que l'on fait osciller ou vibrer pour produire une surface de réaction. Les particules migrent vers le bas dans le plateau ou bac et le produit réactif migre vers le haut dans le plateau ou bac alors que le produit réactif atteint l'état souhaité. On peut ainsi recycler des gaz aspirés.
