Abstract
Cellulosic single fibers such as cotton are prepared without any resins or pitches to a mass or bulk such as a lap which is self-shaped and retains its form by a force of cohesive intertanglement of fibers. The mass as prepared is heated for carbonization or graphitization, if desired, to obtain unique shaped carbides of porous and stable structures in which the cohesion of fibers is made more dense on account of the total shrinkage of the mass by carbonization.
