[0002] The graphite high-temperature purification furnace is mainly used for high-temperature treatment of graphite powder and is an important development direction of a high-purity graphite production process. The raw material for purifying graphite includes aggregate, binder and impregnating agent. The aggregate is usually needle-shaped petroleum coke and pitch coke, and a certain proportion of pitch coke is also used to improve the mechanical strength of the product.
