Abstract
GRAPHITES damaged by radiation grow in the direction of the c-axis and shrink in the direction of the a-axis1. Kelly2 was able to account for the contraction of the basal plane by assuming that the Poisson ratio effect, the layer lattice vacancies and the layer plane buckling are caused by interstitial clusters. Similar contraction has also been observed in lamellar compounds of graphites3,4. In a carbon obtained by baking graphite oxide, the regular lattice was restored at about 2,000° C as in the highly irradiated graphites.
