Abstract
New chalcogenide glasses from the GeSe2–GeTe–PbTe system were synthesized. The glass forming region was determined using visual, X-ray diffraction and scanning electron microscopy analyses. It is extended towards the GeSe2 and lies partially on the GeSe2–GeTe (0–58mol% GeTe) and GeSe2–PbTe (20.0–57.5mol% PbTe) sides. No glasses were obtained in the GeTe–PbTe system. The investigated physicochemical properties vary between 4.04–6.21g/cm3 (density, d); 97–121kgf/mm2 (microhardness, HV); −0.187÷0.007 (compactness, C) and 14.3–17.8GPa (elasticity modulus, E), respectively.
