High‐Temperature Behavior of Beryl and Beryl Melts at High Pressure
View through CrossRef
The pressure dependence of the nonreversible thermal decomposition of natural beryl was examined between 15 and 50 kbars using the high‐pressure “belt” apparatus. The principal products of decomposition are silica, phenacite, and chrysoberyl. As the pressure is increased the thermal stability of beryl decreases and the thermal stability of the decomposition products increases. Silica crystallizes from beryl melts as coesite at the higher pressures and as quartz at the lower pressures.
