It’s impossible to image the semiconductor industry without quartz. Quartz crucibles (special shaped pots for metal melt), quartz tubes, other equipment (cuvettes, cups, containers) are used to obtain single-crystalline silicon. Furthermore, quartz powder is needed to reduce losses of large diameter crucibles to reinforce their inner surface.
Electronic industry requires high purity quartz to avoid contamination during the process of silicon recovery.
Attempts to obtain silicon of “solar quality” directly from quartz with the help of carbothermic reduction reaction have become more intense in recent years.
