Synthesis and characterization of Bi1-xNdxFeO3 (0 ≤ x ≤ 0.3) prepared by thermal decomposition of Bi1-xNdx[Fe(CN)6]·4H2O

The series of polycrystalline heteronuclear complexes, Bi1-xNdx[Fe(CN)6]·4H2O (0 ≤ x ≤ 0.3), was successfully synthesized and characterized, by means of powder X-ray diffraction (PXRD) and infrared spectroscopy. The thermal behaviour was studied by thermogravimetric and differential thermal analysis...

It was found that they crystallized in the orthorhombic crystal system, space group Cmcm. The lattice parameters and unit cell volume decrease with an increase in Nd concentration. In order to obtain the oxides Bi1-xNdxFeO3, the thermal decomposition of the inorganic complexes, Bi1-xNdx[Fe(CN)6]·4H2O, has been investigated.
