文摘

•: The annealing of TeO₂-based glasses show growth of anti-glass spherulites.
•: The textures are similar but different to those in polyamorphic Y2O3-Al2O3 liquids.
•: Diffraction data for the tellurite glasses shows a discorded network formed from TeO3 and TeO4 polyhedra.
•: The growth of spherulites is the nucleation of disordered anti-glass nano-crystals possibly accompanying the growth of a lower density glassy form.
