Graphite Petroleum Coke (GPC), also called GPC, plays a crucial role in many industrial processes. It is used for everything from the carburization of steel to the carbon-rich lithium-ion battery. This extremely pure form of carbon comes from the oil refining process and contains minimal impurities. This material is ideal for industrial uses because it has low sulfur content, a high amount of fixed carbon and no ash.
This is achieved by heating the carbon raw material to a complete crystalline state in a delayed coaling unit. This process is called graphitization. GPC manufacturing is more cost-effective than the synthetic process that has been used in the past.
GPC’s low emissions is one of its most important benefits, along with its purity and its efficient production process. This is because it produces less smoke than other forms of carbon, making it a safer and more environmentally-friendly choice for industrial applications. Additionally, because GPC is produced from petroleum, it is a much more environmentally-friendly source of carbon than other graphite products made from alternative materials such as coal or natural gas.
GPC's crystalline structure, along with its high carbon and low sulfur contents, makes it a perfect recarburizer in the steelmaking and foundry industries. Furthermore, its relatively low nitrogen content means that it is an ideal refractory, as well. The low content of nitrogen makes it a preferred refractory in many industries.
GPC's ability to resist high temperatures is another major advantage. It has an extremely high thermal resistance, and it also conducts very well. This material is up to five times as conductive as steel. Moreover its resistance against corrosion and chemic attack is superior than other materials like copper and aluminium.
In order to achieve this, it can be used as a refractory material, in special machine parts and bearings. The excellent lubrication properties of this material make it an important component for metallurgical processing, such as ingot casting or silicon ingot production. In fire safety, expandable graphite (a GPC specialized version) is extremely valuable for its fire-retardant properties.
GPC's high diffraction modus is closely related to its crystal morphology. Polygranular graphite (a porous, interconnected network of crystalline domains) is the reason for its high diffraction modulus. The diffraction module is higher than that of other graphites with similar structures.
GPC's environmental toxicity is considered low. It has minimal effects on the marine ecosystem. When the product discharges near coastal regions, the seawater pH may temporarily increase, but the effect will dissipate as soon as sufficient water depth and exchange occurs.
