The Chalcogenide glasses were fabricated by melting and quenching techniques in the Se-Ge system at the presence of 1mol% Ga and 3, 5, and 7mol% Sn. Differential Scanning Calorimetry (DSC) analysis was conducted to extract the heat treatment of the samples. Fourier Transform Infrared (FTIR) spectroscopy analysis was also performed in a range of 2-16µm. The Glass samples were heat-treated at 450°C for 1-10h. The precipitated nanoparticles were observed using a Field Emission Scanning Electron Microscope (FESEM). The crystal size was reported in the range of 100-1000nm. The precipitated phases were identified using X-ray Diffraction (XRD) analysis on Glass-Ceramics powder. The increase in hardness of the Glass-Ceramics was reported in the range of 200-250Kg.mm-2.
