METHOD OF ACTIVATING MIXTURE FOR PRODUCING FOAMED GLASS Russian patent published in 2013 - IPC C03C11/00 C03B19/08 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of activating a mixture for producing foamed glass. Starting components for producing the mixture are first ground to the required dispersion of the material - glass, which contains SiO₂, Al₂O₃, RO, R₂O, Fe₂O₃ and soot. The step for mixing components involves activation of the mixture for producing foamed glass by further addition of solutions of alkali metal sulphates S^2- 0.75-6H to the composition of crude materials. Concentration of alkali metal sulphates in the mixture ranges from 5 to 10 wt % in excess of 100%. Components of the mixture are in the following ratio, wt %: SiO₂ - 61.0-73.0, Al₂O₃ - 0.5-3.0, RO - 10.0-15.0, R₂O - 13.0-17.0, Fe₂O₃ - 0.1-0.3, C - 0.6-3.0, S -5.0-10.0. Further, the mixture is foamed and fired in a furnace in order to obtain the end product - foamed glass.

EFFECT: activation of pore-formation and gas phase growth processes and low foaming temperature of the material.
