Abstract
Unusual droplet microaggregates are observed in TeO2-rich glasses of t he systems TeO2-B2O3, TeO2-GeO2, TeO2-B2O3-GeO2, and TeO2-GeO2-V2O5. A decrease of the TeO2 content is established in the aggregates in comp arison with the matrix. Their appearance is related to the process of metastable liquid-phase separation at high viscosity of the melts.
