Abstract

The properties of the glasses and crystals of Ge_xSe₉₀_-_xSb₁₀ (x=20, 23, 25, 30) prepared with melt quenching method have been analyzed by DSC. The glass transition temperature (T_g) of Ge_xSe₉₀_-_xSb₁₀ glasses at different heating rates, the specific heat capacity and the entropy of the glasses and the crystals have been obtained. And on this basis, the kinetics ideal glass transition temperature (T₀), the thermodynamics ideal glass transition temperature (T_K) (Kauzmann temperature) and the kinetic fragility index (m) of Ge_xSe₉₀_-_xSb₁₀ glasses have been determined. It is found that T_g, the specific heat capacity and the entropy increase with increasing the heating rate. T_g and T₀ first increase and then decrease with increasing the Ge content, while T_K increases linearly with the increase of Ge content. The m, T_g/T_K, T_g/T_m and T_g/T₀ are estimated to be 20.7~23.2, 1.183~1.352, 0.678~0.742 and 1.006~1.019, respectively. For each Ge_xSe₉₀_-_xSb₁₀ glass in this work, its m is smaller than 30 and T_g/T_K is larger than 1.1, which means that the Ge_xSe₉₀_-_xSb₁₀ glass should be considered as a strong melt. The value of T_g/T_m is larger than 2/3, which indicates that amorphous Ge_xSe₉₀_-_xSb₁₀ can be formed easily.

Key words: Ge_xSe₉₀_-_xSb₁₀ glass glass transition temperature specific heat capacity kinetic fragility
