Advantages of Graphite Blocks
1.?High temperature resistance: graphite melting point is 3850 + 50 ℃, boiling point is 4250 ℃, even by the ultra high temperature arc ignition, weight loss is small, thermal expansion coefficient is small.Graphite with temperature increase and strengthen the intensity, at 2000 ℃, the intensity of graphite double.
2.?Conductivity: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.
3.?Lubricating property: the lubricating property of graphite depends on the size of graphite scales. The larger the scale, the smaller the friction coefficient and the better the lubricating property.
4.?Chemical stability: graphite has good chemical stability at room temperature, acid, alkali and organic solvent corrosion resistance.
5.?Plasticity: graphite has good toughness and can be ground into very thin sheets.
6.?Thermal shock resistance: when graphite is used at room temperature, it can withstand the drastic change of temperature without damage. When the temperature changes abruptly, the volume of graphite does not change much and cracks will not occur.
