Recently, the Advanced Laser and Optoelectronic Functional Materials Department of the Shanghai Institute of Optics and Precision Mechanics, Chinese Academy of Sciences, has made new progress in the corrosion mechanism of alkali aluminophosphate glass. The research findings were published in The Journal of Physical Chemistry C under the title "Formation Mechanism of Crystal Phase during Corrosion of Aluminum Phosphate Glasses".

Alkaline aluminum phosphate glass has important applications in the solidification of nuclear waste glass and other fields. Among them, chemical stability is crucial for its application. To gain a deeper understanding of the chemical stability of glass, it is necessary to understand its chemical corrosion mechanism. The study of glass corrosion mechanisms has a long history, but there are still many controversies. Previous research has mainly focused on borosilicate glass, while there has been less research on the corrosion mechanism of phosphate glass.

In this study, researchers conducted atomic scale analysis of the structure of alkali aluminum phosphate glass before and after corrosion using various advanced nuclear magnetic resonance techniques, and found that there were two different dissolution modes of the Q1 and Q0 groups in the glass in aqueous solution. This confirms that the crystal layer on the surface of phosphate glass originates from the dissolution of glass components and subsequent deposition on the glass surface. Revealed the dissolution mechanism of alkaline aluminum phosphate glass in aqueous solution and the formation mechanism of surface crystal layer. The research results deepen our understanding of the chemical stability mechanism of alkaline aluminum phosphate glass.
