Abstract  

Thermal behaviour of the glass series (100–y)[0.5ZnO0.1B2O30.4P2O5]yTiO2 (with y=0–39 mol% TiO2) was investigated by DSC and TMA. The addition of TiO2 results in a non-linear increase of glass transition temperature. The compositional dependences of thermal stability, evaluated by two criteria exhibit two maxima for the glasses doped with 10.7 and 35.9 mol% TiO2. All the glasses crystallize on heating in the temperature range of 576–670C. The crystallization mechanism was studied at the glasses with 19.4 and 35.9 mol% TiO2 and the results showed that surface nucleation mechanism prevails in these glasses over the internal one.
