| Abstract: | Negative thermal expansion material of Hafnium tungstate is rapidly synthesized by CO2 laser.The phase structure is characterized by Raman spectra,powder X-ray diffraction（XRD） and scanning electron microscopy（SEM） respectively.The results show that the samples which are cubic structure with minor contents of orthorhombic phase and composed of nanostructures which grow horizontally on the surface.The nano-rods in the interior are composed of densely packed nano-crystallites with grain sizes around 10~50nm. |
