The influences of finely dispersed metals on the heating process of carbon (so-called catalytic graphitization) were investigated. Moreover, the components deposited by catalytic action of metals were heat-treated at higher temperature in order to examine their thermal stability by use of X-ray diffraction technique. The carbons were prepared from phenol resins to which following organometallic compounds were added; Fe (CH₂COCH₂-COCH₃) ₃, Co (CH₂COCH₂COCH₃) ₂, Ni (CH₂COCH₂COCH₃) ₂, C₅ H₅ FeC₅ H₅, C₅ H₅ NiC₅ H₅, Al (OiC₃ H₇) ₃ and Si (OC₂ H₅) ₄. Turbostratic structure components were deposited in carbons containing Ni, Fe and Co after heating above 1000°C and in those containing Al and Si above 2200C. X-ray parameters of these components were slightly changed during further heating up to 2800°C. On the basis of values of their X-ray parameters, these turbostratic structure components were divided into three groups, that is, the component having the highest crystallinity, d₀₀₂: 3.40-3.41Å, L_c (₀₀₂): 140-160Å, was deposited in carbons containing Al and Si. On the contrary, the lowest crystallinity, d₀₀₂: 3.42 ₅-3.43 ₅Å, L_c (₀₀₂): 70-80Å, was observed in the component in carbons containing Co and Fe. The component in carbons containing Ni was intermediate between them. On the whole, their X-ray parameters were characterized by somewhat smaller values of crystallite size than that in graphitizing carbon having the same interlayer spacing as those of these components.
