Fastening the amorphization process of chalcogenide glasses by mechanical alloying
Résumé
In this paper, the possibility to fasten the amorphization process of chalcogenide glasses by mechanical alloying is described. Several ways were investigated to optimize the time of milling permitting a faster production and also avoiding a higher contamination. Thus, the influence of gallium addition which could act as a solvent because of its low melting point and its low vapor pressure has been studied. Then, two conventional ways of milling were compared using a PM100 planetary grinder and a SPEX MILL 8000D, which present two different ways of rotation. Finally, the pollution by WC during mechanical alloying and by carbon during sintering has been investigated by LMS measurements.
