Cokes - Carbon and Graphite
Petroleum coke, as far as quantity is concerned, is the most important raw material, and it is formed in a wide range of structures – from highly anisotropic needle coke to nearly isotropic fluid coke. The highly anisotropic needle coke, due to its structure, is indispensable for the manufacture of high-performance electrodes used in electric ...
Cokes and Material Solutions | Asbury Carbons
Asbury is a world-wide reliable source for both green and calcined petroleum coke (CPC) products. These high-quality, non-graphitic carbons can be found in applications ranging from foundry products and wear moderators for PTFE compounds, to reducing agents and drilling additives. Green coke contains approximately 15-20% residual hydrocarbon materials, while CPC offers a fixed carbon content between 97 and 99.5% and is virtually free of all residual hydrocarbons and moisture.
Needle Coke - Mott Corporation
Needle Coke. Needle coke is used to produce graphite electrodes that are consumed in steel and aluminum production furnaces. A Mott filter can be utilized to filter the needle coke production feedstock to remove contaminants and help ensure the consistent production of a high-quality needle coke product.

Graphite Electrode & Needle Coke Special Report | CRU
From the perspective of graphite electrode production, the "crowding-out effect" of low-cost and inferior quality products has become rather salient in recent years. Statistics compiled by ICC News show the total supply of needle coke in China in 2013 amounts to 161,000 tons, down 17% from 2012, among which imported needle coke accounts for 40%.
International Needle Coke & Graphite Electrode
Needle coke is a special type of petroleum coke with extremely high graphitizability. It is used as a filler material in manufacturing graphite electrodes for electric-arc furnaces to produce iron and steel. Properties of needle cokes, in particular the coefficient of thermal expansion (CTE), control the performance of graphite electrodes.
