Production
High purity graphite is a high purity, fewer impurities. This depends on the complete production process and production equipment.
Special properties of graphite
1. High-temperature resistance: Graphite melting point is 3850± 50℃, the boiling point is 4250℃, even after ultra-high temperature arc burning, weight loss is minimal, the thermal expansion coefficient is insignificant. With the increase of temperature, the strength of graphite increases At 2000℃, the power of graphite is doubled.
2. Conductivity, thermal conductivity: The conductivity of graphite than the general non - metallic ore 100 times higher. The thermal conductivity exceeds that of steel, iron, lead, and other metallic materials. The thermal conductivity decreases with temperature, and even at very high temperatures, graphite becomes adiabatic. Graphite conducts electricity because each carbon atom in graphite forms only three Covalent bonds with other carbons, each of which remains one free electron to carry the charge.
3. Lubricity: the lubrication performance of graphite depends on the size of graphite scales, the larger the scale, the smaller the friction coefficient, the better the lubrication performance.

Application field
(1) Lithium battery industry
Natural graphite and artificial graphite are the primary sources of graphite anode materials. Artificial graphite generally needs to go through calcination, carbonization, high-temperature graphitization, coating, and other technological processes; Natural graphite is mostly purified by alkali acid dressing, ultra-high temperature purification, surface, and other processes.No matter natural graphite or artificial graphite must undergo graphitization or wash at high temperature, to become a cathode material for lithium battery production. At present, high-temperature graphite purification technology, high-temperature graphitization technology, has become the key technology in the research field of graphite anode materials.
(2) Graphene industry
Compared with various preparation methods of graphene, graphite oxide reduction method will become the most promising and promising method to synthesize graphene and its materials. The primary raw material of graphite oxide reduction method is high purity natural flake graphite.
