Abstract

Peculiarities of the influence of cesium cations on the formation of calcium phosphates at the coprecipitation from aqueous solutions of the systems Ca2+—Cs+—M+—PO43–—NO3– (M+ — Na+, K+) (at the molar ratios Ca2+/PO43– = 1.67; M+/Cs+ = 1.0 and 2.0) have been investigated. The samples have been characterized using the powder X-ray diffraction method, FTIR-spectroscopy, scanning electron microscopy, and elemental ana lisys. It is found that cesium cations cause the formation of phases based on α-Ca3(PO4)2 at the precipitation from aqueous solutions.
