Electron microscopy studies of FCC carbon particles Original Research Article

A modified form of carbon was found among the products of a plasmachemical synthesis. This form has a face central cubic (fcc) crystal structure with a lattice constant a = 3.57 A. The fcc carbon takes the form of particles of various shapes (round, ellipsoidal, faceted). The faceted particles have six, eight or ten faces. Within some particles various structures with higher density were observed. Some particles have a more dense core or envelope. The fcc carbon is interpreted as a metastable form of pure carbon.
