text: Contrary to the usual diagram for the conversion of silica to tridymite (the diagram shows cristobalite requiring higher temperatures), silica in the temperature regime of 867 and 1470 degrees C will most often convert to a disordered cristobalite phase favored by free-energy considerations rather than tridymite.
