Crystal structure and negative thermal expansion properties of solid solution Er_2W_(3-x)Mo_xO_(12)

A series of solid solutions Er2W3-xMoxO12(0.5≤x≤2.5)were successfully synthesized by the solid state method.Their crystal structures and negative thermal expansion properties were studied by high temperature X-ray powder diffraction and the Rietveld method.All samples with rare earth tungstates and ...
