Viscosity measurements in halide melts

Viscosity measurements in halide melts
Viscosity measurements in halide melts
Viscosities of two kinds of halide melts were measured at temperatures near the glass transition and above the melting point. The melts and glasses investigated were two fluoroaluminate glasses, a cadmium mixed halide and a cadmium halide phosphate glasses, and a gallium-indium fluoride glass. The fluoroaluminate glasses were designed as core and cladding for a Nd-doped 1.3µm fibre amplifier, while the cadmium halide and cadmium phosphate glasses, were designed as core and cladding for the Pr-doped 1.3µm fibre amplifier. The gallium fluoride glass was also designed as host for the Pr-doped amplifier. The cadmium mixed halide glass exhibits a strong non-Newtonian behaviour contrasting with near-Newtonian fluoroaluminate melts. The implications of these results on fibre drawing and low-loss fibre fabrication are discussed. Viscosity data were fitted to models, and the nappropriateness of the fits is discussed.

Abstract

Viscosities of two kinds of halide melts were measured at temperatures near the glass transition and above the melting point. The melts and glasses investigated were two fluoroaluminate glasses, a cadmium mixed halide and a cadmium halide phosphate glasses, and a gallium-indium fluoride glass. The fluoroaluminate glasses were designed as core and cladding for a Nd-doped 1.3µm fibre amplifier, while the cadmium halide and cadmium phosphate glasses, were designed as core and cladding for the Pr-doped 1.3µm fibre amplifier. The gallium fluoride glass was also designed as host for the Pr-doped amplifier. The cadmium mixed halide glass exhibits a strong non-Newtonian behaviour contrasting with near-Newtonian fluoroaluminate melts. The implications of these results on fibre drawing and low-loss fibre fabrication are discussed. Viscosity data were fitted to models, and the nappropriateness of the fits is discussed.
