摘要：
Colloidal spherical particles with narrow size distribution, of mixed compounds of copper and rare earth ions, were obtained by ageing solutions containing Cu(NO3)(2) + L(NO3)(3), (L = Gd, Dy, Ho, Er) in the presence of urea. The amorphous products consisting of mixed basic hydrous carbonates of Cu and L were converted by calcination to the corresponding ternary oxides with well-defined composition. Composition and magnetic properties of these oxides are discussed.
