Abstract:

The composite material of bamboo charcoal pottery(BCP)was made from pottery and bamboo charcoal powder as the major materials, which was manufactured by mixing, shaping, drying, calcining, testing and analying process. BCP was characterized by scanning electron microscopy, X-ray diffraction, infrared radiation, raman spectroscopy, and specific surface area test to get the crystal structure, pore structure, adsorption,infrared emissivity, and others. The results showed that: Bamboo charcoal particles embedded in the clay matrix and kept their origin mesoporous structure. In addition the Bamboo charcoal particles bear the structure characterization of graphite. The BCP prepared in this manuscript possesses larger specific surface area and its pore structure is dominated by mesoporous.It could be absorb noxious gases such as formaldehyde and benzene efficiently. A certain amount of bamboo charcoal can improve the far-infrared emissivity of BCP.It is higher than the pottery and bamboo charcoal. Through analysis of Fourier transform infrared spectroscopy, we can conclude that the essence of BCP with high infrared emissivity is due to the double-frequency absorption, molecular group vibrations, rotation and lattice vibration.
