摘要：

Scheelite molybdates (MMoO4, M=Ba, Sr and Ca) were successfully prepared by the reactions of M(NO3)(2)center dot 2H(2)O and Na2MoO4 center dot 2H(2)O in propylene glycol and NaOH using a microwave radiation. The phases were detected using XRD and SAED. TEM analysis revealed the presence of micro-sized bi-pyramids with a square base, nano-sized particles in clusters, and dispersed nano-sized particles for BaMoO4, SrMoO4 and CaMoO4, respectively. Diffraction patterns of the bi-pyramids were simulated, and are in accord with the experimental results. Raman and FTIR MoO2- spectra provide the evidence of scheelite structure with Mo-O stretching vibration in 4 tetrahedrons at 742-901 cm(-1). (c) 2007 Elsevier B.V. All rights reserved.
