Editing Quartz (section)

== Piezoelectricity ==
Quartz crystals have [[piezoelectricity|piezoelectric]] properties; they develop an [[electric potential]] upon the application of [[Stress (mechanics)|mechanical stress]].<ref>{{cite book |author1-last=Saigusa |author1-first=Y. |year=2017 |chapter= Chapter 5 – Quartz-Based Piezoelectric Materials |editor1-last=Uchino |editor1-first=Kenji |title=Advanced Piezoelectric Materials |series=Woodhead Publishing in Materials |edition=2nd
