Thermal Stability and Structure of Tellurite Glass

摘要：

　　Oxyfluoride tellurite glass with the composition of TeO2-AlF3-LaF3-ZnO/ZnCl2/ZnF2 was prepared successfully.The thermal stability and structure of TeO2-AlF3-LaF3 system tellurite glass were studied by DSC and IR spectra.The results indicated that glass transition temperature of TeO2-AlF3-LaF3-ZnO/ZnCl2/ZnF2 glass was higher than that of (1-x)TeO2-xAlF3 (x=10%,20%,30%,40%,50%,in mol%) binary glass system slightly.A small number of ZnF2/ZnCl2/ZnO (5mol%) improved glass thermal stability.After adding 5mol% ZnF2/ZnO/ZnCl2 into fluoride tellurite glass respectively,glass transition temperature increased in turn.The introduction of 5mol% different zinc compounds had a little impact on the glass network structure.
