Thermal stability and structural studies in the TeO2–ZnO–MgO–Li2O–Er2O3 glass system
Series of (80-x)TeO2-18ZnO-1MgO-1Li2O-xEr2O3 glass system (0.5mol%=x= 2.5mol%) has successfully been made by melt quenching technique. The thermal stability and structure of glass has been investigated by means of TG/DTA and FTIR spectroscopy. The thermal parameters, such as the glass transition tem...

The thermal stability and structure of glass has been investigated by means of TG/DTA and FTIR spectroscopy.
