Cristobalite
Because cristobalite begins as round silica sand, this material has the same chemical composition as quartz, but in this case there is a unique crystalline structure. This material is formed by heating silica sand in a high-temperature kiln that reaches a temperature in excess of 2,500 degrees F. Cristobalite does exist naturally in some ...

The effect of surface heterogeneity between α-quartz and α-cristobalite
The primary purpose of this work was to elucidate the effect of surface heterogeneity between α-quartz and α-cristobalite on adsorption behaviors toward Cu 2+ ions. Firstly, the macroscopic adsorption isotherms of Cu 2+ ions on α-quartz and α-cristobalite were determined, also thermodynamic change was detected by isothermal titration calorimeter. . …

Conversion to cristobalite occurs more rapidly with finer quartz. This plate, created by Kala Stein (https://kalastein), suffered the effects of cristobalite while she was an adjunct professor at Alfred University. A fairly dramatic bump at 482°F (250°C) due to cristobalite volume changing 7% most likely split the plate.

In situ characterization of phase transitions in cristobalite under
It was established that cristobalite has two phase transitions: 'cristobalite I↔II' at a pressure of 1.2 GPa, and above 13 GPa 'cristobalite III'. The same phase transitions were observed with X-ray powder diffraction [4]. In general, similar behavior of the RS was observed for cristobalite under non-hydrostatic compression in our study.
