At atmospheric pressure it has no melting point, as its triple point is at 10.8 ± 0.2 MPa and 4,600 ± 300 K (4,330 ± 300 C; 7,820 ± 540 F), so it sublimes at about 3,900 K (3,630 C; 6,560 F). [21] [22] Graphite is much more reactive than diamond at standard conditions, despite being more thermodynamically stable, as its delocalised pi system is much more vulnerable to attack.
Calcined Petroleum coke comes from delayed coke which extracted from oil refinery. Although calcined petroleum coke contains high content of sulfur and nitrogen It is widely used to produce graphite electrode, graphite blocks, brakes pads and other carbon products.
Petroleum coke appliion Petroleum coke can be used in the industries of graphite, smelting and chemical industry depending on its quality. 1.Low-sulfur, high-quality cooked coke, such as needle coke, is mainly used to manufacture ultra-high-power graphite

The best material is synthetic graphite, then petroleum and pitch coke, and the least favourable material is anthracite. Yet the problem is that materials from all of these groups are similar in their chemical analysis, with carbon content variation only in the range of 1%–2% (98%–99.7% C for the synthetic graphite grades, 97%–99% for petroleum coke and 93%–95% C for anthracite) [ 6
This premium-grade, high value petroleum coke is used in a variety of appliions, including the manufacture of graphite electrodes for electric arc furnaces in the steel industry. A highly crystalline form of carbon, it is typically higher in carbon and lower in ash constituents, such as sulfur and metals, than standard calcined petroleum coke.
When this high melting point distillate wax is mixed with ordinary paraffin wax, the mixture has a melting point higher than the melting point 60 of wax mixtures calculated from the formula x.s + Y.-S X+Y -S given by J. Kisser in Z Wiss.
Ultra-clean isotropic coke is obtained from bituminous coal by extracting such coal following the extraction procedure described in U.S. Pat. No. 4,272,346, issued Jun. 9, 1981, to Stiller et al., using, for example, N-Methyl Pyrrolidone as the extraction solvent, and
Tungsten is a metal with a particularly high melting point (which has made it suitable for use as a filament in incandescent bulbs); ionic compounds such as granite have high melting points
The present invention provides a needle coke for graphite electrodes, wherein a needle coke, used as a raw material coke, comprises a coke of 100 parts by weight, to which adheres a substance of 0.03 to 16 parts by weight having a softening point, or a melting
