Abstract—A novel method for preparing a batch of silicate glasses containing crystalline quartz, glass formers, modifiers, intermediates, and auxiliary components, including the physicochemical activation of high-melting batch components with the use of alkali metal hydroxides, is developed. The optimal technological parameters are determined and the general scheme for obtaining an agglomerate by the proposed method is presented. It is found that moisturizing the activated components of a glass batch with a KOH solution having a minimal concentration of 0.5% strengthens the agglomerate of the glass batch in comparison with moisturizing by water.
Keywords: glassmaking, physicochemical activation of raw materials, compaction of glass batch, metal hydroxides
