MIT Captures Salt Crystal Migration in Real Time

A team at MIT has visualized salt crystal migration, known as “salt creep,” at the single-crystal scale for the first time using X-ray microscopy. The breakthrough has wide-ranging implications for desalination, civil engineering, and cultural heritage conservation.

Understanding how salt crystals reshape and trigger chain reactions could lead to more effective coatings and drainage systems, preventing salt-induced damage in infrastructure and industrial systems.
