The mixed amorphous glassy-type zirconium-titanium phosphates contain various quantities of adsorbed water per molecule unit. Pure zirconium phosphate lost the structural water in two steps. This character disappeared with increasing titanium content. However, glassy titanium phosphate lost its water in two steps at lower temperature in comparison with glassy zirconium phosphate.


Das gemischte amorphe Zirkonium-Titan-Phosphat enthält pro Moleküleinheit verschiedene Mengen adsorbierten Wassers. Reines Zirkoniumphosphat verliert das strukturelle Wasser in zwei Schritten. Diese Eigenschaft verschwindet mit zunehmenden Titangehalt. Amorphes Titanphosphat verliert sein Wasser in zwei Schritten bei niedriger Temperatur im Vergleich zu amorphem Zirkoniumphosphat.
