Unusual droplet microaggregates are observed in TeO 2 ‐rich glasses of the systems TeO 2 –B 2 O 3 , TeO 2 –GeO 2 , TeO 2 –B 2 O 3 –GeO 2 , and TeO 2 –GeO 2 –V 2 O 5 . A decrease of the TeO 2 content is established in the aggregates in comparison with the matrix. Their appearance is related to the process of metastable liquid‐phase separation at high viscosity of the melts.
