International ClassH05B 006/02AbstractThe 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.Other References
