This invention relates to an improved process for the thermal dehydrogenation of polysilicon granules in a fluidized bed reactor, the improvement which comprises introducing a varying electromagnetic field into the reactor whereby reactor walls are coated with silicon during the dehydrogenation.

Silicon coating process

The inductive heating of a reactor vessel by an external electromagnetic heating source is made more uniform by placing a susceptor between the heating source and the reactor vessel. In preferred embodiments, the reactor vessel is a fluidized bed vessel made of graphite and suitable for the preparation or treatment of polysilicon particles, and the susceptor is also made of graphite.
