The room-temperature form of quartz, α-quartz, undergoes a reversible change in crystal structure at 573 °C to form β-quartz.This phenomenon is called an inversion, and for the α to β quartz inversion is accompanied by a linear expansion of 0.45%.This inversion can lead to cracking of ceramic ware if cooling occurs too quickly through the inversion temperature.

Quartz Inversion In ceramics, this refers to the sudden volume change in crystalline quartz particles experience as they pass up and down through 573C. Fired cracks are often related to this. Glossary: Cristobalite Inversion In ceramics, cristobalite is a form (polymorph) of silica. During firing quartz particles in porcelain can convert to ...

The phenomenon is especially prevalent in solids. From an intuitive point of view, the failure of the body to be "absolutely stable" is a consequence of the observation that at a given temperature and pressure, which would ordinarily cause the body to adopt a well-determined configuration, more than one configuration is observed.

The axis inversion phenomenon depends on the cut angle of the substrate. Dimension control of the axis inverted area is possible using a metal film pattern. Applications of the x-axis inversion phenomenon are proposed. For example, a configuration composed of two resonators with different modes on an AT-cut quartz plate is represented.

In meteorology, an inversion, also known as a temperature inversion, is a deviation from the normal change of an atmospheric property with altitude. It almost always refers to an inversion of the thermal lapse rate.Normally, air temperature decreases with an increase in altitude. During an inversion, warmer air is held above cooler air; the normal temperature profile with altitude is inverted.
