英文摘要	The syntheses and structures of er2-xcexw3o12 were studied. it was found that pure phases could form only for 0.0 <= x <= 0.4 and 1.5 <= x <= 2.0. compounds with 0 <= x <= 0.4 have the hydrated orthorhombic structure at room temperature and transform to unhydrated orthorhombic one above 135 degrees c whereas samples with 1.5 <= x <= 2.0 crystallize in monoclinic structure. thermal expansion properties of er2-xcexw3o12 were studied with high temperature x-ray powder diffraction. samples with 0 <= x <= 0.4 exhibit negative thermal expansion in temperature range of 200-800 degrees c and higher cerium content leads to more negative thermal expansion coefficient. however, compounds with 1.5 <= x <= 2.0 show positive thermal expansion owing to the edge-sharing polyhedra.
