Quartz crystals are also a common component in devices like cell phones, television receivers, and, of course, watches and clocks. One of the main reasons quartz is used in so many electronic devices is because it is piezoelectric, meaning it generates an electric charge when pressure is exerted upon it.

Quartz is the second most abundant mineral in the Earth's continental crust, after feldspar. It is made up of a continuous framework of SiO4 silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall formula SiO2. There are many different varieties of quartz, several of which are semi-precious gemstones.

Quartz samples used in this study were two grades of commercially available ground silica (US Silica MIN-U-SIL 5 and SIL-CO-SIL 250) with average grain sizes of 5 μm and 250 μm, respectively, and SiO 2 contents of 99.3% and 97.3%, respectively. The feldspar samples we used were collected from Miyake-Jima Island, Japan, and were composed of more than 99% albite (NaAlSi 3 O 8).
