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 SiO, AlO, RO, RO, FeOand soot. The step for mixing components involves activation of the mixture for producing foamed glass by further addition of solutions of alkali metal sulphates S0.75-6H 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 %: SiO- 61.0-73.0, AlO- 0.5-3.0, RO - 10.0-15.0, RO - 13.0-17.0, FeO- 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.1 tbl |
