FIELD: chemistry.
SUBSTANCE: invention relates to silica microspheres. Silica microsphere precursors are added to hydrocarbon-doped induction plasma. Said precursors, specifically powdered silicate or quartz glass and silica microspheres are premixed with water and at least one additive which is an expander and/or binder and/or flux.
EFFECT: higher content of silica and lower content of impurities in silica microspheres.
