Effects of Sintering Temperature on the Phase Changes of Woodceramics Prepared from Liquefication Wood

Abstract

Discarded wood was liquefied with phenol to prepare the liquefication basic woodceramics (LBW). The effects of sintering temperature on the phase changes had discussed. The Fourier transform infrared (FT-IR) analysis showed that, as sintering temperature rose, the elements of H and O were excluded gradually, as well the circle C-C structure had formed. The X-ray diffraction (XRD) analysis indicated that higher sintering temperature could improve the microcrystal structure. With the temperature increasing, (002) diffraction peak became strong and the diffraction angle 2θbecame larger, meanwhile, the stacking height of larger plane and the crystallite size increased also. In addition, the distances of interlamination drop drown, and the rank of microcrystal became more regulation and order. Butgvalues which character the degree of graphitization always were less than zero, and the integrated graphite structure had not found, suggesting the LBW was a kind of a difficult graphitization material.
