Thermal properties of Ga2S3-based glass and their consideration during fiber drawing

Thermal properties of Ga2S3-based glass and their consideration during fiber drawing
Thermal properties of Ga2S3-based glass and their consideration during fiber drawing
Thermal properties of gallium-lanthanum sulphide and oxysulphide glasses relevant to fiber applications are evaluated. Time-temperature-transformation diagrams of gallium-lanthanum sulphide and oxysulphide glasses are presented based on the results of X-ray diffraction analysis and microstructural observations. Thermal stability of these glasses for fiber drawing is discussed along with the viscosity data of supercooled liquid samples. Favourable fabrication conditions for gallium lanthanum sulphide glass fibers are proposed to minimize microcrystal formation during heating.

Abstract

Thermal properties of gallium-lanthanum sulphide and oxysulphide glasses relevant to fiber applications are evaluated. Time-temperature-transformation diagrams of gallium-lanthanum sulphide and oxysulphide glasses are presented based on the results of X-ray diffraction analysis and microstructural observations. Thermal stability of these glasses for fiber drawing is discussed along with the viscosity data of supercooled liquid samples. Favourable fabrication conditions for gallium lanthanum sulphide glass fibers are proposed to minimize microcrystal formation during heating.
