Firing: What Happens to Ceramic Ware in a Firing Kiln

This material has many more forms than quartz, so it is a complex animal to say the least. However, while almost all bodies have some quartz, you won't have a problem with crystobalite inversion unless there is crystobalite in your body. Crystobalite forms naturally and slowly during cooling from above cone 3.

Precise formation technique of x-axis inversion regions on ...

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.

Quartz inversion - WikiVisually

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.
