- •
Transformation of AlPO4-5 into AlPO4-tridymite was realized by heating with water.
- •
5">In situ multinuclear MAS NMR was used to study the phase transformation.
- •
Water first activates residue amorphous phase to transform into AlPO4-tridymite.
- •
5">Water participates the transformation by hydrolysis and condensation reaction.
- •
Water establishes the mass transportation between AlPO4-5 and AlPO4-tridymite.
