Chalcogenide Glasses. Part 3. Chalcogenide Glass-Forming Systems.

This report summarizes the literature search on glass-forming regions of chalcogenide compositional systems. Brief discussions on physical, chemical and structural properties are also included. This study was conducted to select and evaluate the chalcogenide glasses which are suitable for use in graded optical filter applications. Continuous variations of optical properties may be achieved by continuously varying the compositions of multicomponent glasses. The usefulness of this approach is severely limited in some multi-component glasses because of their tendency for phase separation and crystallization, which lead to inhomogeneous microstructures.
