AlPO
4 x 1.5H
2O was found to be more soluble than the better known dihydrate (variscite, AIPO
4 x 2H
2O) hence proving to be metastable. This material was determined to undergo incongruent dissolution at pH around 3.0 and higher producing initially amorphous Al(OH)
3 which gradually (within 30-day dissolution period) converted to the stable gibbsite phase.
