A silicate-containing aqueous solution composition comprising: a) from 10 % w/w to 50 % w/w of a silicate compound selected from sodium and potassium silicates, or a mixture of such silicate compounds; b) from 1 % w/w to 5 % w/w of a salt, the cations of which are selected from sodium and potassium ions, and the anions of which are selected from halogen, sulfate and carbonate ions, or a mixture of such salts; c) from 0.25 % w/w to 5 % w/w of ethylene glycol; and d) water. The silicate compound is preferably sodium silicate, especially sodium silicate having an average formula of Na2SiO3, Na6Si2O7, Na2Si3O7, or Na2Si4O9, or mixtures thereof. The salt is preferably sodium chloride. The composition is useful in encapsulating pollutants, fireproofing flammable materials and extinguishing fires. |
