摘要：

Phosphate and silicate materials exhibit similar structures but their solution chemistry is very different. Polyphosphates cannot be synthesized under ambient conditions from PO(OR)3 or PO(OH)3 solutions. More convenient PO(OH)3-x(OR)x precursors have been obtained via the dissolution of P2O5 in alcohols. Their reactivity towards hydrolysis and condensation depends on x and the alkyl group. They have been used as precursors for the sol-gel synthesis of titanium phosphates. P-31 NMR experiments show the formation of P-O-Ti bonds during the course of the reactions.
