A new family of rare-earth silicate compositions and the synthetic methods used to prepare them. The materials have open-framework structures and are characterized by their ion-exchange properties. They are represented by the following empirical formula:AMM'SiOwhere A is an exchangeable cation such as sodium, M is at least one element selected from the group of rare-earth elements, and M′ is a framework metal having a valence of +2, +3, +4, or +5. The rare-earth silicate materials have utility in various cation-exchange applications such as dialysis and removal of toxic metals from the gastrointestinal tract.
