Thermal properties and stability of TeO2 containing phosphate glasses
Original language description
Differential thermal analysis and thermodilatometry have been used to study the thermal behaviour of glasses in the ZnO-P2O5-TeO2 system prepared in compositional series(100?x)[0.5ZnO-0.5P2O5]-xTeO2 (X-series) and 50ZnO-50?y)P2O5-yTeO2 (Y-series) withinthe concentration range of x = 0-60 and y = 0 40 mol% TeO2. The addition of TeO2 to the starting zinc metaphosphate glass resulted in a gradual increase of thermal expansion coefficient from 12.2 up to 16.6 ppm?C?1, whereas glass transition temperature and dilatometric softening temperature reveal a minimum at the glass with x = 30 mol% and y = 10 mol % TeO2. All glasses crystallize on heating within the temperature range ?500-700 ?C. The contribution of the surface crystallization mechanism over the internal one increases with increasing TeO2 content. Major compounds formed by crystallization were Zn(PO3)2 and Zn2P2O7.
