Graphite rods and the difference between carbon graphite rods and the carbon rods‌‌

Graphite rods and the difference between carbon graphite rods and the carbon rods of the main difference is that the material composition, manufacturing process and the chemical and physical properties: graphite rod made of graphitization treatment of carbon materials, resistant to high temperature and electrical conductivity is strong; Carbon rods are made of ungraphitized carbon materials, which have better chemical stability but lower hardness. Material composition and manufacturing process of graphite rod: raw materials for the natural graphite with a mixture of petroleum coke and pitch coke, the high temperature graphitization treatment (3000 ), carbon atoms are arranged in graphite crystal structure. 1 hard, high temperature (about 3850 ), melting point, excellent electrical conductivity and thermal conductivity. 23 carbon rod: made of carbon materials (such as carbon powder, binder) extrusion molding, sintering temperature is only about 1000 , not through graphitization process, internal to the amorphous carbon structure. 14 hardness is low, but excellent chemical stability, resistance to acid and alkali corrosion. 4: effect on physical and chemical properties of graphite rods conductivity is stronger, is often used in electrodes (such as steel-making arc furnace); Carbon rods have relatively weak electrical conductivity, but they are suitable for arc cutting of metals. 3 high temperature resistance, graphite rod structure at high temperature stability, is suitable for smelting; Carbon rods have slightly inferior high-temperature resistance, but they can meet the needs of most industries. Mechanical properties: graphite rod brittle is higher; Carbon rods have better tensile strength, but they are fragile. 34 applications graphite rod: steel electrode, semiconductor hot field components, high temperature furnace heating elements. 2 elements: metal cutting, such as stainless steel, cast iron electrode, spectral analysis, chemical reactor lining.
