摘要：

FIELD: chemistry. SUBSTANCE: invention relates to technology of obtaining halogenide-containing silicon. Halogenated polysilane is thermally decomposed with continuous addition into reactor at the range of temperatures 350°C-1200°C and at pressure from 10 -3 mbar to 1.3 bar. Silicon has content of halogenide from 1% at to 50% at. EFFECT: obtaining sort of silicon, which can be applied for purification of metallurgical silicon. 21 cl, 1 ex
