GPC, or Graphite Petroleum Coke, is an essential part of many modern industrial processes. This material is vital to the advancement of key industries including steelmaking and other metal-based products. The superior thermal stability, machinability and conductivity of this high-purity material make it highly sought after. Silvari Group offers a range of GPC products to suit various applications, from fine granules to large chunks. Before calcination, our GPC undergoes screening and pretreatment to eliminate impurities. A high-quality, crystallized form of Carbon is produced.
GPC composition is dependent on pet coke type and processing. It is pretreated and screened to check for purity, quality, and ash levels. This helps remove any inhomogeneity of large particles in pet coke. The final product must be consistent and of a high standard.
After the pretreatment process, the pet coke is oxygenated and coked at high temperatures to produce a coke with increased carbon content and lower volatile materials. During the coking process, the carbon atoms in the coke are aligned in a crystalline form that makes it ideal for further processing to make graphite. The coke undergoes a graphitization procedure that involves heating it to extreme temperatures. This creates a form of crystalline carbon which has excellent thermal stability. One of the most significant characteristics of graphite coke petroleum is its thermal stability. This can provide an advantage to other alternatives.
The process improves the conductivity of the final product and makes it suitable for high-temperature uses such as electric arc furnaces. In addition, the high-purity graphite produced during this process is less prone to oxidation and can be used in critical industrial processes that require high-temperature resistance.
The morphology Graphite Petroleum Coke is very diverse, ranging anywhere from tiny flakey pieces in fine powders up to needle-like grains and irregular structures in the coarser products. The density of the pet coke is also a factor in its final application, with higher-quality calcined coke typically having a much higher density than raw pet coke without calcination.
GPC with a thickness of 0-5mm plays a vital role in several industries, such as battery manufacturing and steelmaking. Due to its high purity level and unique characteristics, it's a superior alternative to carbon-based materials used in industrial applications. GPC's production is sustainable, using byproducts rather than crude oils from petroleum refinement. For this reason, it is widely considered a more environmentally friendly option.
