Study on Fe/Woodceramics composites

Fe/Woodceramics (Fe/WCMs) composites are prepared by dipping bamboo powder into ferric salt solution, dropping alkali, mixing with furane resin, and then having the mixture molded and finally sintered in high temperature. Microstructures of Fe/WCMs are measured by using X-ray diffraction (XRD) and scanning electron microscopy (SEM). XRD results indicate that the characteristic peaks of Fe are found. SEM photographs show that Fe crystals are distributed in the glassy carbon. The effects of concentration of ferric salt on volume shrinkage ratio and volume electrical resistivity of the composites are investigated. The results show that the volume shrinkage ratio and the volume electrical resistivity decrease with an increase in concentration of ferric salt.
