Synthesis of GeSe4 glass by mechanical alloying and sintering
Résumé
The possibility to synthesize GeSe4 glass by mechanical alloying followed by sintering has been demonstrated. X-ray diffraction (XRD) and differential scanning calorimetry (DSC) analysis have been performed on the powder as a function of milling duration in order to follow the amorphization process of raw metallic germanium and selenium elements. Completely amorphous powder has been sintered using a homemade hot press. Optical transmission and the density of the final bulk material have been studied
