Alkaline earth modified germanium sulfide glass |
| abstract |
A sulfide glass with improved mechanical and optical properties such as extended transmission in the infrared region of radiation having wavelengths of up to about 15 microns; Tg in the region of 410 DEG -550 DEG C.; and thermal stability of 100 DEG -300 DEG C. based on the difference between Tg and Tx, comprising, on mol basis, 20-90% germanium sulfide, 0-60% gallium sulfide, and 5-60% of at least one modifier in sulfide form. A process for improving mechanical and optical properties of a sulfide glass based on gallium sulfide and/or germanium sulfide comprises the steps of mixing glass components, including a modifier in elemental or sulfide form; melting the glass components to form a molten mixture; cooling the molten glass mixture to a solid state; annealing the solid glass; and cooling the annealed glass to about room temperature. The glass components can be in elemental form or in the form of sulfides, and if in elemental form, then sufficient amount of sulfur is added to form sulfides of the glass components. |
