Paper Title:
Synthesis of MnWO4 Nano-Particles by Low-Temperature Molten Salt Method
  Abstract

Manganese tungstate nano-particles were successfully synthesized at low temperatures by molten salt method, and characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and ultraviolet visible spectra techniques (UV-vis), respectively. The effects of calcining temperatures and salt quantity on the crystallization and development of MnWO4 crystallites were studied. Experimental results showed that the well-crystallized MnWO4 nano-particles with about 40 nm in diameter could be prepared at 270°C with 3:1 mass ratio of the salt to MnWO4 precursor for a holding time of 4 h. XRD analysis evidenced that the product was a pure monoclinic phase of MnWO4 with wolframite structure. UV-vis spectrum revealed that MnWO4 nano-particles had strong light absorption properties in both ultraviolet and visible light region.
