The content of sulfur in aphanitic graphite ore is generally low, mostly 0.26% ~ 1.16%. Amorphous graphite is the most abundant one in graphite, with small scale and low crystallinity. It is used to produce low-value products and is the lowest one in graphite; It is mainly contained in Turkey, China, Europe, Mexico, and the United States.

Graphite has been of great interest since the dawn of the nuclear era. In this work, we will focus on the thermal neutron scattering of two types of nuclear graphite that have different microstructures, namely, the historic PGA which has a very anisotropic medium-grained needle coke, and the new G347A which is a near-isotropic fine-grained graphite.

Abstract. The Stone–Wales (SW) transformation, or carbon-bond rotation, has been fundamental to understanding fullerene growth and stability, and ab initio calculations show it to be a high-energy process. The nature and topology of the fullerene energy landscape shows how the I h-C 60 must be the final product, if SW transformations are fast enough, and various mechanisms …
