Overview

Randomized trial investigates corrosion behavior of boro-alumino-phospho-silicate glass, suggesting in situ transformation mechanisms.

Key Points

  • This research aims to elucidate the corrosion mechanism of boro-alumino-phospho-silicate glass in aqueous environments.
  • Investigation of corrosion behavior using solid-state nuclear magnetic resonance (SSNMR) and scanning electron microscopy (SEM) techniques.
  • Analysis focused on the formation of amorphous alteration layers and phase separation in the glass under various conditions.
  • Confirmation of nanoscale phase separation into aluminum phosphorous-rich and aluminum silicate-rich domains.
  • Observation of gelation in aluminum phosphorous-rich domains while the aluminum silicate-rich domains remained vitreous, forming a mixed gel layer.
  • Evidence supports an in situ transformation mechanism as primary, involving preferential hydrolysis and selective leaching of phosphorus.
