Abstract
Abstract Glasses of Ge25-xGaxTe75-yIy system with gallium content of 5–15 at.% and iodine of 0–6 at.% have been prepared. The glass transition temperature, crystallization and melting temperature of the samples in the range 100–400 °C were determined by differential scanning calorimetry. In Ge15Ga10Te75-yIy system, the crystallization stability of glasses is extremely dependent on composition, taking the maximum value for y = 2; for Ge10Ga15Te75-yIy and Ge25-xGaxTe69I6 systems, a monotonous increase in the resistance to crystallization with an increase in the content of iodine and gallium is characteristic. The density of the glasses, measured by the hydrostatic weighing method, decreases with increasing of y. In view of physicochemical and optical properties among the investigated samples, the glasses of Ge15Ga10Te73I2 and Ge10Ga15Te69I6 are the most suitable for drawing optical fiber. Optical fibers are manufactured from these glasses by crucible method.
