摘要：The furnace comprises a treatment zone (30), a gas inlet (22), a chamber forpreheating the gas present between the inlet and the treatment zone, a susceptor

comprising a side wall (12) around the chamber and the treatment zone, and an inductor(18) for heating the side wall. The side wall has three recesses uniformly or regularlyspaced apart from each other to form portions of reduced thickness on a part of sidewall. The recesses are arranged on inner periphery or outer periphery of side wall of thesusceptor. The furnace comprises a treatment zone (30), a gas inlet (22), a chamber forpreheating the gas present between the inlet and the treatment zone, a susceptorcomprising a side wall (12) around the chamber and the treatment zone, and an inductor(18) for heating the side wall. The side wall has three recesses uniformly or regularlyspaced apart from each other to form portions of reduced thickness on a part of sidewall. The recesses are arranged on inner periphery or outer periphery of side wall of thesusceptor. A portion of the side wall comprising the recesses has a thickness of 30-60%of the thickness of the side wall. The recesses have a height, which is lower than theheight of the preheating chamber, and a width of 15 cm. The side wall of the susceptor isformed of an upper shell surrounding the charging zone and a lower shell surroundingthe chamber. The lower shell comprises the recesses, and a unit for supporting an upperplate of the chamber. The recesses are provided with an electrically insulating material.The inductor is connected to a tension generator having a frequency of 50-1000 Hz.
