The Relations between Tridymite and Cristobalite

The Relations between Tridymite and Cristobalite

T116-T125 (10 pages)

In the course of a long series of experiments, no obvious loophole was left by which one could escape the conclusions regarding the stability relations which have been drawn. At temperatures above 1470±10°, quartz, tridymite and amorphous silica have repeatedly and unequivocally been converted into cristobalite; between 1470±10° and 870±10°, quartz cristobalite, and amorphous silica have similarly been converted into tridymite; and below 870±10° tridymite, cristobalite, and amorphous silica have been converted into quartz. These relations have been confirmed again and again. Moreover, recent work by Ferguson & Merwin has indicated that the melting point of tridymite is considerably lower than that of cristobalite. It follows necessarily from this observation that cristobalite is the high temperature form.
