Paper Title:
Coprecipitation Synthesis and Negative Thermal Expansion of R2Mo3O12 (R = Y, Yb)
  Abstract

In this research, powders of Y2Mo3O12 and Yb2Mo3O12 were successfully synthesized by liquid phase coprecipitation, followed with a heat treatment at 750°C for 6h. X-ray diffraction (XRD) analysis indicated that the Y2Mo3O12 and Yb2Mo3O12 were single orthorhombic structure with the space group of Pbcn. Negative thermal expansion properties of Y2Mo3O12 and Yb2Mo3O12 were studied with high temperature XRD analysis. The thermal expansion coefficients of Y2Mo3O12 and Yb2Mo3O12 were calculated to be -5.943×10-6K-1 and -6.237×10-6K-1 respectively.
