Production of amorphous silicon, useful for producing highly pure or coated amorphous silicon, purification or production of organohalosilane, especially methylchlorosilane, involves reducing halosilane with metal, optionally in solvent

摘要

In the production of amorphous silicon (a-Si) by reducing halosilanes with a metal, reduction is carried out in the presence of an apolar solvent, which is not necessary in the case of fluorosilanes.
