Phosphate ceramics were synthesized using the sol-gel technique of direct reaction of P{sub 2}O{sub 5} with tetraethoxy silane (TEOS) or titanium tetraethoxide (Ti(OEt){sub 4}). The reaction mechanism of P{sub 2}O{sub 5} and TEOS was deduced using liquid and solid-state NMR. Hexacoordinated silicon in phosphosilicate gels was observed. A specially structured titanium phosphate-layered Ti(HPO{sub 4}){sub 2}{center_dot}2H{sub 2}O was synthesized for the first time through the sol-gel method. The gelation process and sintering properties were investigated. {copyright} {ital 1998 Materials Research Society.}
