The Replacement of Quartz Sand with Microsilica for Obtaining Glass Materials

The article presents the physicochemical and technological characteristics of amorphous silica fume. According to the results of experimental studies, it can be established that the replacement of natural quartz sand with ferrosilicon waste–microsilica in the glass charge does not reduce its main physical, chemical and technological characteristics. It is shown that the replacement of quartz sand with microsilica in the raw material composition of the glass charge leads to a decrease in the temperature of smooth formation, in particular, glass melting, as a result of which it helps to save natural raw materials and energy resources, while solving the problems of improving the environmental situation in the industrial region of the Republic.
