Research of electrohydraulic destruction of mineral quartz

Quartz is the most common mineral with the chemical composition of SiO2 (46.7 % — Si, 53.3 % — O2). In practice, quartz crystals extremely rarely approach this composition, since they usually contain various impurities. At present, ground quartz is widely used in various industries. For example, in the production of refrac-
