| Outline of Final Research Achievements |
Mesophase, which is very important structure for carbon materials, is a spherulite having anisotropic structure and is known appearance of magnetic oriented like a liquid crystal. It is presumed that the extent of its expression depends on the size and density of the crystallite, however, its details have never known. Using the mesophase pitch made from anthracene as a raw material. We analyzed the size and oil content of crystallites on magnetic orientation quantitatively, and examined the optimum environment for the magnetic field effect. For the synthesis of highly oriented carbon material precursor by magnetic orientation, it is necessary to contain a large amount of raw material low molecular weight hydrocarbons and a condition with high crystalline size and small crystallite number. Since low molecular weight hydrocarbons volatilize at high temperatures, a mechanism to hold them is also necessary, and high pressure conditions are effective countermeasures against this.
