Stability of Titanyl Hydrogen Phosphates in Aqueous Media

Resumo

We have studied the hydrolytic stability of titanyl hydrogen phosphates in relation to their composition, the synthesis procedure, and the nature and concentration of the electrolyte. The chemical stability of these compounds can be improved by increasing the electrolyte concentration and decreasing the degree of hydration of metal cations in solution and also by modifying their composition with metal cations differing in acid–base properties from titanium(IV). We have found conditions that maximize the hydrolytic stability of the titanyl hydrogen phosphates.
