Distribution of Silica Particles in a Bilayer Arsenic Sulfide Fiber during Double-Crucible Drawing

Abstract

This paper presents results of physical and computational experiments aimed at gaining insight into the behavior of silica impurity particles in two flowing contacting glass melts (core and cladding melts in the arsenic sulfide fiber drawing process). It has been shown that the particles present in the cladding melt are uniformly distributed, without passing into the core melt or concentrating at the interface between the two layers of the fiber. Theoretical calculations have been confirmed by experimental data.
