N2 - An attempt was made to prepare a carbon sample having a highly oriented structure from poly(acrylonitrile) by using a two-dimensional opening between the lamellae of montmorillonite as the field of carbonization. The carbon prepared at 700°C was liberated from montmorillonite and then it was subjected to heat treatment at various temperatures up to 2800°C. The characteristics of the resulting carbon were determined by microscopic, diffractometric, spectroscopic, and magnetoresistance methods. The graphitizability of the carbon is very high, and the carbon heat-treated at 2800°C has almost the same characteristics as the ideal graphite crystal. It consists of graphitic films with Lc value of about 40 nm and very large La value of more than 1 μm in many cases.
