Resumo |
Bulk SixTe100-x (10 less-than-or-equals, slant x less-than-or-equals, slant 28) glasses have been prepared by the melt quenching technique. The crystallization of these glasses has been studied by using differential scanning calorimetry. The composition dependence of the glass transition temperature Tg, the recrystallization temperature Tcr and the melting temperature Tm show an unusual behaviour at the composition x congruent with 20. The glasses with 10 less-than-or-equals, slant x less-than-or-equals, slant 20 undergo double glass transition and double stage crystallization phenomena. On the other hand, glasses with 22 less-than-or-equals, slant x less-than-or-equals, slant 28 exhibit eutectic crystallization. The phases at different stages of crystallization have been identified by using X-ray diffraction techniques. The unusual behaviour at x congruent with 20 can be explained on the basis of the changes in the network topologies of IV-VI chalcogenide glasses. |
