Paper Abstract

Controlled crystallization of a glass of the As-Ge-Se system, nucleated by hafnium resulted in production of glass-ceramics with better thermomechanical properties than the starting glass while conserving good IR transmission in the 7-12μm range. This range is extended to 15μm by the addition of hafnium . The mechanism, of devitrification is investigated as well as the evolution of IR transmission with temperature.
