Summary:Possibility of obtaining nanoscale silica from the dust of dry gas cleaning of silicon production by thermal methods is considered in the report. Analysis of the chemical and granulometric compositions of the initial dust, dust after annealing in the muffle furnace is given. A new technology for the thermal-vortex enrichment of dust of dry gas cleaning of silicon to obtain nanosilica is proposed, the results of modeling and laboratory studies are presented.
