Graphite function mainly has six points:

1) graphite high temperature resistant: Graphite melting point is 3850 ± 50 ℃, the boiling point is 4250 ℃, even after high temperature arc ignition, graphite weight loss is very small, the coefficient of thermal expansion is very small.

2) graphite conductive, thermal conductivity: conductive graphite is one hundred times higher than the general non-metallic minerals. Graphite conductive graphite is because each carbon atom and the other carbon atoms form only 3 covalent bonds, graphite each carbon atom retains 1 free electrons to transfer charge.

3) graphite lubrication: lubrication performance depends on graphite in graphite flake size, scale is larger, the smaller the coefficient of friction, the better the performance of graphite lubricant.

Chemical stability: 4) graphite graphite has good chemical stability at room temperature, acid, alkali corrosion resistance and organic solvent.

5) graphite plasticity: graphite has good toughness, but year into very thin sheets.

6) the thermal shock resistance of graphite: dramatic changes in graphite can withstand temperature at ambient temperature with time and can not be damaged, temperature change, volume change of graphite, no crack.

Graphite has high temperature resistant, conductive, heat conduction, chemical stability, lubricating, plasticity, thermal shock resistance of these functions, so that the graphite is widely used in various industries.
