The exact transition temperature depends on the crystallinity of the cristobalite sample, which itself depends on factors such as how long it has been annealed at a particular temperature.
22.
In 1995 the Soufriere Hills volcano on the Caribbean island of Montserrat erupted, spewing volcanic ash containing large amounts of the crystalline silica mineral cristobalite over the surrounding area.
23.
Silicosis is due to deposition of fine respirable dust ( less than 10 micrometers in diameter ) containing crystalline silicon dioxide in the form of alpha-quartz, cristobalite, or tridymite.
24.
Otherwise, melanophlogite is thermally stable and its physical properties do not change upon 20-day annealing at 800 �C, but it converts to cristobalite after heating at temperatures above 900 �C.
25.
Soapstone undergoes transformations when heated to temperatures of 1000 1200 �C into enstatite and cristobalite; in the Mohs scale, this corresponds to an increase in hardness to 5.5 6.5.
26.
The persistence of cristobalite outside of its thermodynamic stability range occurs because the transition from cristobalite to quartz or tridymite is " reconstructive ", requiring the breaking up and reforming of the silica framework.

28.
This change saw a drastic population shift of Cristobalites to new areas in Margarita and Coco Solo, and the redefinition of territorial boundaries which reduced the extension of the Canal Zone on Manzanillo Island.
29.
They have a chunky, blocky appearance, exhibit a layered structure with abundant vesicles, and contain mineral inclusions, such as zircon, baddeleyite, chromite, rutile, corundum, cristobalite and coesite.
30.
These different twin orientations coupled with the discontinuous nature of the transition can cause considerable mechanical damage to materials in which cristobalite is present and that pass repeatedly through the transition temperature, such as refractory bricks.
