Abstract
Based on the conducted research, it is proposed to use the waste of the enrichment of ferruginous quartzites of KMA as the main raw material for the production of fire-filtered glass silica. The regularities of the formation of the phase composition of glass silica with the formation of such crystalline phases as hematite and hypersthene are established. Based on experimental studies using X–ray phase, differential thermal analysis and IR spectroscopy, a mechanism for the formation of the phase composition of glass silica is proposed. The advantages of the developed technology in comparison with analogues are shown. It was found that after plasma chemical modification, such performance indicators of the front surface of glass silica as water resistance, acid resistance, alkali resistance and hardness significantly increase.
