摘要
Structural inspection of carbonized woodceramics impregnated with liquefied wood was performed by dimensional shrinkage and weight loss, the content of carbon and oxygen with X-ray energy dispersive analysis (EDS), Raman scattering spectroscopy, laser microscope observation and X-ray diffraction. The results showed that with the increasing temperature, the dimensional shrinkage, weight loss and the ratio of carbon to oxygen in woodceramics increased, the (002) interplanar spacing of the crystalline component in woodceramics decreased and the value of R increased above 650degreesC. Woodceramics have a turbostratic structure with cracks, and internal stresses etc., especially for those carbonized at temperatures over 650degreesC. (C) 2002 Elsevier Science Ltd.
