What Is The Stability And Shelf Life Of Trisilver Triiodide?

Trisilver triiodide (Ag3I3) is an unstable compound that tends to decompose over time, especially when exposed to light or heat. Its shelf life is relatively short and highly dependent on storage conditions.

Specifically, trisilver triiodide is known to undergo a phase transition at around 25°C, where it transforms from a reddish-orange alpha phase to a yellow beta phase. This transition is accompanied by a significant decrease in stability, with the beta phase being much more prone to decomposition than the alpha phase.

Overall, trisilver triiodide is not considered a suitable material for long-term storage or practical applications due to its instability and susceptibility to degradation.
