Graphite Petroleum Coke (GPC) is a premium carbon material that can be utilized in many industrial applications. It is an essential ingredient in the production of artificial graphite that is among the most vital raw materials used in lithium ion batteries. The metallurgical coke has a higher thermal conductivity than natural graphite, which makes it ideal for lithium-ion battery electrodes. It's also more durable than natural graphite, which can help increase the longevity of the battery. In addition the low content of silica in Graphite Petroleum Coke helps prevent the formation of dust particles which could reduce the battery's efficiency and life span.
In contrast to coal non-coking coke doesn't vaporize in the absence air. It is a solid residue that is compacted by impregnation. This process transforms the amorphous carbon from the raw petroleum coke into a densified, crystalline graphite product. The treatment process improves the mechanical properties and increases the crystalline structure of graphite. Graphitized petroleum is used in the steel industry, precision casting and as a reduction pregnant agent for metallurgical processes. It is also used to manufacture graphite electrodes, which are vital for modern metallurgical processes.
Depending on how the coke is processed it can be converted into a variety of types. Examples include calcined petroleum coke needle coke green delayed petroleum coke, and oil needle coke. The cokes differ in appearance, color and texture. Moreover, they can vary in their porosity, hardness, and strength. The type of coke best suitable for metallurgy will be based on the needs of the customer.
In the case of Needle Coke, for example it has a unique structure that is comprised of needle-shaped crystals, with the c direction being oriented in a single direction. This allows it to be more conductive than other forms. It is a great raw material for the production of graphite of high-quality that can be used in the production of lithium-ion batteries. Its unique structure makes it a great option for thermal applications.
To ensure the quality of Needle Coke, it is subjected to rigorous tests. To determine the thermal conductivity of the product, it is subjected to a temperature range between 2500 to 3000 degC. The thermocouple is connected to a temperature graph. The data is then analysed using an analyzer for thermal data.
In addition to its thermal conductivity Needle Coke is known for its low thermal expansion as well as outstanding electrical conductivity. It is the perfect raw material to make high-quality graphite that can be used in a range of industrial applications. Its low impurity level and uniform morphology make it a perfect raw material for the manufacture of batteries as well as other products that require a high-performance.
