Engineering, Central South University, Changsha 410083, China; 2. State Key Laboratory of Powder Metallurgy, Central South University, Changsha 410083, China) Abstract: Bulk isotropic pyrocarbon materials... mechanism was proposed. The results show that the bulk isotropic pyrocarbons which are fabricated in 10-40 h, at 1 000-1 300 ℃, are mainly composed of the spherical pyrocarbon granules. With density......
