In this paper, are compared the non-isothermal crystallization kinetics of two investigated rich selenium glasses SeXSb (X=In, Zn). We found that the systems exhibit high glass transition and crystallization temperatures Tg and Tc values indicating that they don’t crystallize easily and both glassy systems become less fragile with increasing Sb contents. It’s also seen that the heat of atomization of these systems increases while their activation energy of glass transition decreases with average coordination number. In the other hand, according to Dietzel and Hrubý criteria, the glassy system SeZnSb becomes more stable with high Sb contents, corresponding to high activation energy of crystallization, making it suitable candidate for PC-RAM devices, while SeInSb exhibits the opposite behaviour..
