Complex phosphates containing mono-and trivalent cations

摘要

The review surveys the data on the synthesis,structures,thermal stability and physical properties of complex phosphates contianing M~I ad M~(III)cations generated from double phosphates by the partial replacement M~I->H~+ or PO_4~(3-)->X~(n-) [X~(n-)=F~-,OH~-,EO_4~(n-) (VO_4~(3-),MoO_4~(2-) or S_2O_3~(2-).The sizes of the M~I and M~(III) cations and their ratio have a domiant role in the structure formation of complex phospates.The prospects of the use of complex phosphates as polyfunctional materials are discussed.The bibliography includes 161 referneces.
