【 摘 要 】

Alloys of Sb10Se90-xGex(x = 0, 19, 21, 23, 25, 27) have been prepared using melt quenching technique. Differential thermal analysis has been used to determine the three characteristic temperatures, glass transition (Tg), glass crystallization (Tc) and melting temperature (Tm), at four heating rates 5, 10, 15 and 20 K/min. The thermal stability and ease of glass formation have been evaluated in terms of Hruby parameter and reduced glass transition temperature respectively. The activation energy for glass crystallization (Ec) has been calculated using Kissinger's method and Marseglia theory. The composition dependence of Tgand Echas also been discussed.
