Abstract
Crystalline and glassy alloys in one of the highest temperature glass-forming systems GeS2–EuS are studied by differential thermal analysis, x-ray diffraction, chemical analysis, and IR spectroscopy. The glass-transition, crystallization, and melting temperatures of the alloys are determined with a high accuracy. The results indicate that, with increasing EuS content, the glass-transition temperature decreases from 492 to 448°C. The most homogeneous glasses can be prepared at EuS contents below 15 mol %. To obtain homogeneous glasses in the range 25–30 mol % EuS, an increased cooling rate is needed: 20–30°C/s.
