Needle coke Needle-like crystals develop.
Low thermal expansion coefficient.
Pitch Produced by heat treatment of coal tar.
Carbonizes under heat (50% yield).
Needle coke and pitch are mixed and then molded. Heat treatment is then applied in the baking and graphitization process to form the finished product.
