METHOD FOR OBTAINING STRUCTURED SILICA ON THE BASIS OF MAN-MADE INDUSTRY WASTE Russian patent published in 2023 - IPC C03B19/09 

FIELD: glass silicate production.

SUBSTANCE: invention relates to the production of glass silicate based on man-made industrial waste used in construction. The method for producing glass-silica based on technogenic industrial waste includes screening, mixing, laying in the forms of the lower layer, grinding, laying in the forms of the upper layer, sintering, annealing, cutting and quality control, and as the glass-containing material of the lower layer, a mixture of wastes from the enrichment of ferruginous quartzites is used. Kursk magnetic anomaly and wastes of vanadium production and liquid glass at a mass ratio of 2:2:1, respectively, and as a glass-containing material of the upper layer - a mixture of container glass granules with liquid glass at a mass ratio of 8:1.

EFFECT: improving the mechanical properties of the final product and reducing energy costs due to sintering at a lower temperature.
