Abstract :
Phase and structural behaviour in the SmAlO3-TbAlO3 system has been studied in a whole concentration range by means of laboratory X-ray diffraction, in situ synchrotron powder diffraction and differential thermal analysis techniques. Formation of the continuous solid solution Sm1-xTbxAlO3 with orthorhombic perovskite structure has been established. Peculiarity of the solid solution is existence of three regions with different relations of the lattice parameters. Based on the results obtained, as well as available literature data for the “pure” SmAlO3 and TbAlO3 compounds, the phase diagram of the pseudo-binary system SmAlO3-TbAlO3 has been constructed.
