Amorphous forms of solid carbon do not have a fixed crystal structure and consist of structural units - nanosized graphene particles. A team of physicists studied the structure of amorphous carbon and suggested classifying it as a separate type of amorphous solid bodies: a molecular amorphic with enforced fragmentation.
