Can silicon dioxide conduct electricity? Silicon dioxide does not conduct electricity under normal circumstances,because in it no free electrons are present for conductivity. It is used as in insulator inside integrated circuits, because it can be grown on the sio2 wafer by exposing it to steam.

However it is piezoelectric, which means that if you deform it it will generate an electrical impulse; and if you apply an electrical field to it it will deform. This property allows it to be used to make resonant crystals to control the frequency of "quartz" watches, radio transmitters/receivers and other devices.
