Reversible Quartz

Reversible quartz typically refers to a phenomenon in quartz crystals where they can undergo transformations that are reversible under certain conditions, such as temperature or pressure changes.

One common example is the transition between different phases of quartz, such as ?-quartz and ?-quartz, which occurs at around 573 °C. This transition can revert back to the original phase when the temperature decreases, illustrating the reversible nature of certain physical properties in quartz.

Additionally, in the context of electronics, reversible quartz can also pertain to its use in piezoelectric devices where it can switch between mechanical and electrical states.
