Processes Occurring in Synthesis of Iron-Containing Glaze Frits

The processes of silicate and glass formation in iron-containing glass mixtures based on technical raw materials (oxides and carbonates) and with the use of igneous rocks - metadiabases are investigated. The distinctive features of their course are revealed depending on the chemical composition of the glass. It has been established that the crystalline phases that have appeared in the process of silicate formation in the form of structural groups in the glass melt are preserved. The possibility of lowering the synthesis temperature of glaze frits using metadiabases is shown. Tab. 2, ill. 3, bibliography: 7 titles.
