We study the characteristics of the graphites by XRD, Raman spectra, FG-SEM. After X-Ray data refined by Rietveld method, the precipitated graphites include both Hexagonal and Rhombohedral crystal.

The highest graphitisation is the artificial graphite which adding 10000ppm Boron the artificial graphite which adding 10000ppm about 93.04﹪. In FGSEM pictures, there are carbon tube (about 10~100nm)on the precipitated graphites. In Raman spectrum, the artificial graphite which adding 300ppm Boron is the most complete because of the highest area ratio of sp2 and sp3. The highest yield is the artificial graphite which adding 10000ppm Boron. YuanHaun Lee 李 源 弘 2001 學位論文 ; thesis 0 zh-TW |
