Randomized trial examines gel layer formation during dissolution of borate glasses, suggesting tunability of ion release.
Key Points
This work aims to investigate gel layer formation on alkali-modified aluminoborate glasses during aqueous corrosion and its implications for bioactive applications.
Investigated sodium- and potassium-modified aluminoborate glasses after dissolution in deionized water.
Analyzed gel formation via bulk monoliths and powder x-ray diffraction techniques.
Conducted ICP-AES analysis of gel and solution to determine ion release dynamics.
Both sodium- and potassium-modified glasses exhibited gel layers primarily composed of amorphous materials, except for one composition forming santite.
Ion release from glass into solution was not inhibited by gel formation, indicating effective ion leaching.
The glass composition significantly affected the tunability of ion release, impacting structural durability.
