Abstract

The fabrication of halide glass fibers is much more difficult when compared with oxide glass fibers. This is because of the high fluidity of most molten halides, their unusual viscosity-temperature characteristics and the poor chemical durability of the glass. Protective coatings are necessary and because of the high expansion coefficients of halide glasses and their relatively low softening temperatures the choice of an ideal coating is difficult. Some of the critical problems associated with fiber formation and the choice of proper coatings are discussed. The effects of the penetration of water through Teflon coatings and that of the presence of crystallites on tensile strengths of fluoride fibers are presented.
