Abstract
The modification of the phases in the mixed ceramics of ferroelastic BiVO4 and ferroelectric GdVO4 has been studied with x-ray diffraction and Raman scattering experiments. We observe evidences that a new phase in addition to BiVO4 and GdVO4 phases exists in the mixed ceramics for 0.3 ≤ × ≤ 0.9. Additional peaks in the x-ray diffraction patterns and new Raman modes are observed.
