Feature:
1.Chemical stability: Graphite has good chemical stability at room temperature. It can resist acid, alkali and organic solvent corrosion.
2.High temperature resistance: the melting point of graphite is 3850 ℃, and the boiling point is 4250 ℃. Even if the graphite is burned by ultra-high temperature arc, the weight loss is very small and the coefficient of thermal expansion is very small. The strength of graphite increases with the increase of temperature, and doubles at 2000 ℃.
3.Conductivity: The conductivity of graphite is 100 times higher than that of non-metallic ores. Graphite can conduct electricity because each carbon atom in graphite forms only three covalent bonds with other carbon atoms, and each carbon atom still retains one free electron to transfer charge.
4.Thermal conductivity: The thermal conductivity decreases with the increase of temperature, even at extremely high temperatures, graphite becomes an insulator. Graphite conducts electricity because each carbon atom in graphite forms only three covalent bonds with other carbon atoms, and each carbon atom still retains one free electron to transfer charge.
