SYNTHESIS OF NEODYMIUM(Ⅲ) GERMANATES IN SOLUTIONS

摘要

The NdCl_3-K_2GeO_3-L(L=H_2O,C_@H_OH) systems were studied by Tananaev's residual concentration method. In both systems, the equilibrium solid-phase composition depends on the initial NdCl_3:K_2GeO_3 ratio, n.From aqueous solutions with n≤0.59 and n=0.91-1.5, Nd_2(GeO_3)_3 and Nd_2Ge_2O_7 precipitate, respectively, From ethanolic solutions with n≤0.75 and 1.61
