FIELD: chemistry.
SUBSTANCE: invention pertains to chemical and electronic industry and can be used for obtaining highly pure silicon. Silicon containing substance is put into a melting pot with molten silicon through a system of pipes with 0.1-5 mm2 openings for obtaining gas bubbles. Thermal decomposition of the silicon bearing gas takes place. The obtained silicon replenishes the melt. The proposed invention allows for increasing output of the process and purity of the obtained silicon at a lower cost of the equipment and energy losses.
EFFECT: increased output of process and purity of obtained product at lower cost of equipment and energy losses.
