I wanted to ask some reference about aluminum nitride hydrolysis in water.
Specifically I would like to know if there is the formation of radicals or of some other reactive species.




I am quoting from this study[[1](https://www.azom.com/article.aspx?ArticleID=3060)]:



> 
> $\ce{AlN}$ powders hydrolyze in moist air at room temperature, resulting in degradation of the powders. The initial hydrolysis product is amorphous $\ce{AlOOH}$, which is further converted to a mixture of polymorphs of $\ce{Al(OH)3}$ (bayerite, nordstrandite, and gibbsite), forming agglomerates around the unreacted $\ce{AlN}$ core. In the hydrolysis each powder shows an induction period, which is attributed to slow hydrolysis of the surface oxide/oxyhydroxide layer. The powders produced by the carbothermal process show the longest induction periods.

You can find a detail explanation of the reaction in that study.
