摘要： A method for the contamination-free heating of a highly pure gas to a temperature of from 300 to 1200° C. involves passing the highly pure gas at a pressure of from 0.1 to 10 bar abs. over a highly pure solid which does not contaminate the gas, the solid being present in a highly pure container whose wall consists of a material which has a transparency of more than 85% for infrared rays and the container being irradiated by means of the infrared rays, the solid being heated thereby and the solid heating the gas.

摘要： A radiation-heated fluidized-bed reactor and a process for producing high-purity polycrystalline silicon by using this reactor are provided. In this reactor, a heater device (14) is a radiation source for thermal radiation which is arranged outside the inner reactor tube and as a cylinder around the heater zone, without being in direct contact with the inner reactor tube. The inner reactor tube is designed in such a manner that it uses thermal radiation to heat the silicon particles in the heating zone to a temperature which is such that the reaction temperature is established in the reaction zone.

摘要： High-purity polysilicon granules are prepared by depositing reaction gas on silicon granules in a fluidized bed reactor having: a reactor space comprising at least two zones lying one above the other, the lower zone weakly fluidized by introduction of a silicon-free gas into silicon granules in the lower zone by a plurality of individual dilution gas nozzles, and a second, reaction zone directly abutting the lower zone, the reaction zone heated via its outwardly bounding wall, introducing silicon-containing reaction gas as a vertical high speed gas jet into the reaction zone by reaction gas nozzle(s), forming local reaction gas jets surrounded by bubble-forming fluidized bed, gas decomposing leading to particle growth, wherein the reaction gas has fully or almost fully reacted to chemical equilibrium conversion before reaching the wall or bed surface.
