Products Specification :
Products detailsFormed by means of CIP (cold isostatic pressing) technique, isostatic graphite is characterized by its homogeneous structure and excellent isotropic electrical, thermal and mechanical properties. Sometimes it is purified in special-designed graphitization furnace to remove non-carbonaceous impurities. It is widely used in a variety of industrial and scientific engineering as a structural and/or functional material.
Products Features :
(1) High temperature resistance
The melting point of graphite is 3850 ± 50 ºC, even if it 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. At 2000 ºC, the strength of graphite is doubled.
(2) Conductivity and thermal conductivity
The conductivity of graphite is 100 times higher than that of ordinary non-metallic minerals. Thermal conductivity exceeds that of steel, iron, lead and other metal materials. The thermal conductivity decreases with the increase of temperature. Even at extremely high temperature, graphite becomes an insulator. 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.
(3) Lubricity
The lubrication performance of graphite depends on the size of graphite scale. The larger the scale is, the smaller the friction coefficient is, the better the lubrication performance is.
(4) Chemical stability
Graphite has good chemical stability at room temperature and can resist acid, alkali and organic solvent corrosion.
(5) Plasticity
Graphite has good toughness and can be ground into very thin sheets.
(6) Thermal shock resistance
Graphite can withstand the drastic change of temperature without damage when used at room temperature
