Abstract. Changes in the structure of two graphitizable carbons and four non-graphitizable carbons were followed by measuring d (002), d (110), Lc (002), and La (110) as a function of HTT. It is observed that graphitizable carbons undergo rapid changes in the structure in the temperature range 2400–3000°C and become polycrystalline graphite.
Abstract. The formation of graphitizing low-temperature carbons by solidifiion from a liquid phase proceeds via the separation of a mesophase having properties similar to those of liquid crystals. Initially, the mesophase, consisting of planar aromatic compounds of high molecular weight, separates in the isotropic liquid as spherical droplets

Samples of graphitizing carbon materials were made from a mixture of dispersed petroleum coke (sulfur content 1.3 wt%) and 25% pitch, which were pressed in the forms of cylinders and carbonized at 900˚C for 3 hours.
Graphitizing and non-graphitizing carbons (alternatively graphitizable and non-graphitizable carbon) are the two egories of carbon produced by pyrolysis of organic materials. Rosalind Franklin first identified them in a 1951 paper in Proceedings of the Royal Society . [1]
Specifiions. As an ideal carbon additive and intermediate reactor, carbon raiser is made from calcined petroleum coke during graphitizing process. Due to its high carbon content, low and consistent S/P content and its porous structure, which allows hot metal to enter the tiny fissures to devour its carbon content quicker, coke is always the best
