Carbon powders derived from a phenolic resin were pre-heated at temperatures between 600° and 1800°C, followed by soaking into chloroform solution of nickelocene (Cp
2 Ni). The carbon powders covered with Cp
2 Ni were heat-treated in the temperature range between 1200° and 1600°C for 1 hour in order to deposite the specific turbostratic structure component (component TS). The component TS which deposited in the carbons pre-heated at below 1200-1400 °C gave nearly equal X-ray parameters,
d002: 3.41Å,
LC(002) : 80Å, regardless of the deposition temperature. Using the phenol resin carbon pre-heated at above 1400°C, the deposited TS component exhibited the decrease of
d002, the increase of
LC (002) and the decrease of its deposition amounts with a raise of pre-heating temperature.
Moreover, the phenol resin with addition of about 4 wt% of Cp
2 Ni was well-mixed and, then, heated at 1000°C for 30 hours. The resulting carbon (TS carbon) consisted most of the TS component
d002: 3.41Å,
d11o: 1.23Å,
Lc (002) and
La (110) : 100Å). These X-ray parameters were not changed even by heating up to 3000°C. TS carbon was characterized by somewhat smaller values of crystallite size and of the strain along the c-axis than those in graphitizable carbons having the same interlayer spacing as that of TS carbon.
