Precise boundaries of phase separation and glass transition in Laponite

Establish the precise boundaries of the phase separation region and the glass transition line in the Laponite system, and construct a unified phase diagram that delineates these boundaries, with particular emphasis on the low-concentration regime.

Background

The authors interpret their results within a nonequilibrium gelation framework involving arrested phase separation and glass formation. While this scenario qualitatively accounts for salt-dependent heterogeneity, they note that the exact locations of the phase separation region and glass transition line are not well defined for Laponite.

A unified and precise phase diagram, especially at low concentrations, would clarify the interplay between phase separation, gelation, and glassy dynamics and enable more predictive control over Laponite-based materials.
