MATERIAL FOR CLARIFICATION AND HOMOGENISATION OF GLASS MASS DURING MELTING OF SILICATE GLASS Russian patent published in 2024 - IPC C03C1/02 

FIELD: chemistry.

SUBSTANCE: invention relates to chemical technologies in the production of glass and environmental protection, in particular, it can be used to produce clarified and homogenised glass. Material for clarification and homogenisation of glass mass during melting of silicate glass is a dry mixture of salts containing calcium and lithium carbonates. Mixture of salts is formed after decontamination of highly acidic mine water of sulphate class at pH 12–13 with reagent Ca(OH)₂ until complete coprecipitation of metals, except lithium, removal of sediment from water, saturation of water with CO₂ with formation of sediment from compounds of CaCO₃ and Li₂CO₃ in water, removal of water from sediment with production of finished product – dry mixture CaCO₃⋅Li₂CO₃.

EFFECT: acceleration and simplification of processes of clarification and homogenisation of molten glass mass during melting of silicate glass.
