Abstract The bucky tubules and bucky onions are synthesized in macroscopic quantity with high yield by modified Kratschmer-L8mb-FostiropoulogHuffman method. Besides ordinary concentric bucky tubules, also are observed abnormal nonconcentric multilayer graphitic tubules with varying layer spacings. The curved graphitic tubules are observed, showing the tendency to form torus. Under appropriate helium pressure, about half of the synthesized product is the multi-shell bucky onions, polyhedral in shape in accord with the theoretical calculation.
