| Abstract: | A new series of solid solution Er2-xHox（WO4）3（x=0.0～0.4,1.2～2.0） have been successfully synthesized by the solid-state method.The crystal structural and thermal expansion properties of solid solution Er2-xHox（WO4）3 have been investigated with X-ray diffraction,and Riveted structural refinement.Negative thermal expansion of compounds Er2-xHox（WO4）3（x =0.0 ～0.4,1.2 ～2.0） are found to be anisotropic along the three crystallographic directions. |
