Ternary phosphates in Ca3(PO4)2-Na3Ln(PO4)2 (Ln-Nd, Eu, Er) systems
- 1. Moskovskij Gosudarstvennyj Univ., Moscow (USSR)
Description
Ternary phosphates, formed in Ca3(PO4)2-Na3Ln(PO4)2 (Ln-Nd, Eu, Er) systems were investigated by the methods of X-ray phase, luminescent analyses and IR spectroscopy. 5 regions of homogeneity were found. Two of them (I and II) were distinguished for all systems. Samples in the region of up to 14.285 mol.% Na3Ln(PO4)2 crystallize on the basis of β-Ca3(PO4)2 structure, and in other homogeneity regions - on the basis of β-K2SO4 structure
