Jan 10, 2014· Carbon and graphite materials are manufactured according to processes based on conventional ceramic technologies.Raw materials such as petroleum cokes, pitch cokes, carbon black or graphite materials with a defined grain size distribution are mixed with a .
The final step in graphite manufacture is a conversion of baked carbon to graphite, called graphitising, i.e. heat-treating the material at temperatures in the region of 2600°C - 3300°C. During the graphitising process, the more or less pre-ordered carbon (turbostratic carbon) is converted into a three-dimensionally ordered graphite structure.
Large scale roll-to-roll production of graphene based on chemical vapor deposition, was first demonstrated in 2010. In 2014 a two-step roll-to-roll manufacturing process was announced. The first roll-to-roll step produces the graphene via chemical vapor deposition, and the second step binds the graphene to a substrate.

In this process, agglomerated graphite grains are produced for use as carburizer and carbon additives. Intercalation. Due to its extreme anisotropy, the graphite crystal enables salts to be intercalation in its structure. When heated, these salts evaporate, causing the disruption of inter-planar connections, "expanding" the graphite.
Graphite Electrode Manufacturing Process 5.Baking. Within the roasting road, will be "green" electrode roasting to the specified temperature, according to the requirements of process after roasting products with special dipping, density, mechanical strength, in order to improve the products and then to repeat the roasting of impregnated products, improve product performance.
