Resumo

Bulk glasses of GeSeIn have been prepared by quenching the melt and have been subjected to thermal crystallization and X-ray structure analysis of devitrified materials. These glasses show a transformation from a single-stage to a double-stage crystallization with respect to composition. The present investigations indicate that these materials are structurally inhomogeneous at a molecular level, in which In2Se3 microclusters are dispersed in the GeSe matrix. These results are discussed using the chemical threshold in glasses.
