Tellurite Nanocrystal Ostwald Ripening

Heat-treated tellurite (TeO₂) glass precipitates a population of nanocrystals that then coarsens by Ostwald ripening: curvature-driven diffusion carries material from small crystals to large ones until the small ones vanish. This simulator seeds a 3D glass matrix with nanocrystals of random starting size and evolves every one of them under a mean-field Lifshitz–Slyozov–Wagner growth law, with a temperature slider controlling the Arrhenius-activated diffusion rate. Live readouts track the surviving crystal count, mean and maximum radius, and the self-consistent critical radius that separates growth from dissolution — the same size-distribution control used to engineer tellurite glass-ceramics for nonlinear and infrared photonics.
