Phase formation during crystallization of melts and glasses of the GaxGe40-xS60 system
Source abstract
Abstract
The purpose of this work is to study phase formation during quenching of glass-forming melts and crystallization of Ga xGe 40- xS 60 glasses ( x = 0–15 at.%), which are promising materials for optical IR glass-ceramics. The stability against crystallization of the glasses is determined to decrease with increasing gallium content. In the case of the glass-forming melts, the stability against crystallization increases in the range x = 0–8 at.% and then decreases. It is established that, during crystallization, not pure phases of binary sulfides are formed, but their solid solutions. When quenching the melts with a gallium content of 10–15 at.%, Ga 2-xGe xS 3 solid solutions, which are isostructural to one of the polymorphic modifications of gallium sesquisulfide, are crystallized. Solid solutions form skeletal crystals, the growth of which leads to the formation of a dendritic crystal structure. Micro-liquation in the Ga xGe 40- xS 60 glasses is observed.
