Abstract

"The ability to form a stable glass and the crystallization properties of four compositions close to that of glaucophane, Na2Mg3Al2Si8O22(OH)2 studied. Three glasses were compared with a fourth glass containing no fluorine. The crystallization products of all four glasses were examined between the temperature range 600 - 1200°C. The crystallization products of the three fluorine containing glasses were similar, consisting of mica below 1000°C and of mica, fluor-glaucophane, enstatite and forsterite above 1000°C. In the fluorine free glass, enstatite was the only crystalline phase present below 1000°C, however, forsterite and enstatite were both present in samples crystallized above 1000°C. It is concluded that, although the fluor-glaucophane compositions could be used to study orientation effects in glass fibers, these compositions are not ideally suited for such a study since it was never possible to crystallize fluor-glaucophane from these compositions without the accompanying crystallization of mica, enstatite, and forsterite"--Abstract, page ii.
