The surface of primary particle of CB consists of randomly ranged finegraphite-like crystals with Fullerene structure carbon, and shows rough atomic steps' morphology.
炭黑原生粒子表面由细小的石墨状晶体无规排列构成，并存在富勒结构碳，呈凹凸不平的原子台阶形貌。

Adding different alloy combination of re, copper and titanium, then through gestation and nodulizing disposal, we got the fine texture of ferrite pearlite and spheroidal graphite.
The process conditions and mechanism of preparing expand graphite by using cheap fine flake graphite as raw material was primarily studied in this paper.
