Experimental study of the possibility of using a silica clay as a source of silicon in the production of glass in the Turkestan region of Kazakhstan

Abstract

Three series of experiments were carried out to study the possibility of replacing quartz sand in the initial charge for the production of glass with a silica clay. The experiments were carried out at atmospheric pressure and temperatures of 900–1200 С. It is shown that the complete replacement of quartz sand with a silica clay and the use of the presented initial compositions based on silica clay in the glass industry will lead to an increase in the temperature in the technological scheme of production, an increase in energy consumption and is economically unprofitable.Production schemes are promising, in which, along with the silica clay, the original charge contains cullet. It is shown that the disappearance of crystalline phases in this case in the samples with the addition of the silica clay occurs at a lower temperature than in the samples without the silica clay.
