Characteristics of graphite:

1) High-temperature resistance: The melting point of graphite is 3850±50°C, and the boiling point is 4250°C. Even if it is burned by an ultra-high temperature arc, the weight loss is very small, and the thermal expansion coefficient is also small. The strength of graphite increases with the increase of temperature, and at 2000°C, the strength of graphite doubles.

2) Electrical and thermal conductivity: The electrical conductivity of graphite is one hundred times higher than that of ordinary non-metallic minerals. Thermal conductivity exceeds that of metal materials such as steel, iron, and lead. Thermal conductivity decreases with increasing temperature, and even at extremely high temperatures, graphite acts as a thermal insulator. Graphite can conduct electricity because each carbon atom in graphite forms only 3 covalent bonds with other carbon atoms, and each carbon atom still retains 1 free electron to transport charges.

3) Lubricity: The lubricating performance of graphite depends on the size of the graphite flakes. The larger the flakes, the smaller the friction coefficient and the better the lubricating performance.

4) Chemical stability: Graphite has good chemical stability at room temperature, and is resistant to acid, alkali, and organic solvents.

5) Plasticity: Graphite has good toughness and can be rolled into very thin sheets.
