Raman Spectrometry Study on the Composite of Bamboo Charcoal Pottery

Abstract:

In this paper a confocal micro-raman spectrometer was used to study the characteristic change of bamboo charcoal pottery(BCP) during its formation from bamboo-charcoal and clay.The effect of carbonization temperature on the carbon bonds and corresponding modes of vibration was detailedly discussed through analysising raman spectrum of the samples.The results showed that the raman spectra of the samples assumes a typical saddle and have no sharp peak, which belong to the typical spectra of carbon material containing amorphous graphite.BCP was mainly pyrolyzed to aromatic substances at low temperature carbonization stage(less than 973K),but didn't form complete graphite crystallite.At low temperature it is pyrolyzed to generate aromatic component, while at 1073K, it becomes hexagonal planar network aggregate composed of sp3 hybridized C atoms, in this case is shows the structure of microcrystalline graphite.With the rise of baking temperature（973K～1373K）, the valne of R representing disorder began to reduce and the value of La standing for the diameter of microlite started to increase which approves that higher temperature is benefit for the growth of amorphous and the enhancement of graphitizing degree.But BCP was also typical non-graphitizable carbon when heat treatment temperature increased to 1373K.
