چکیده
|
A glass-forming domain is found and studied within bi2o3– ta2o5–teo2 system. the glasses obtained in the system ta2o5-teo2 was investigated by dsc, raman and infrared spectroscopy. the influence of a gradual addition of the modifier oxides ta2o5 on the coordination geometry of tellurium atoms has been elucidated based infrared and raman studies and showed the transition of teo4, teo3+1 and teo3 units with increasing ta2o5 content. the density of glasses has been measured. the investigation in the teo2- ta2o5 system using xrd reveals new phases.
