Abstract
A process for producing an optical glass fiber from crystal-glass phase material. In one embodiment, the process includes the step of providing a molten crystal-glass phase material in a container, wherein the temperature of the molten crystal-glass phase material is at or above the melting temperature of the molten crystal-glass phase material, T, to allow the molten crystal-glass phase material is in liquid phase. The process further includes the step of cooling the molten crystal-glass phase material such that the temperature of the molten crystal-glass phase material, T, is reduced to below Tto cause the molten crystal-glass phase material to be changed from the liquid phase to a viscous melt. Moreover, the process has the step of pulling a glass fiber of the crystal-glass phase material from the viscous melt, wherein Tsatisfies the following relationship: T<T<T, and Tbeing the temperature at which the vitrification of the viscous melt of the crystal-glass phase material occurs, and wherein the crystal-glass phase material is characterized by having a reversible thermal behavior.
