High Strength Graphitized Petroleum Coke
Graphitized petroleum coke has high electrical conductivity due to the large number of π bond electrons. At high temperatures, the distance between the graphite layers of graphitized petroleum coke will further expand, resulting in a decrease in the energy of the π bond within the layer, making it more conductive.
Description
Description
The electronic structure of graphitized petroleum coke is also the key to conducting electricity. The electron structure of graphitized petroleum coke is mainly composed of π electron and σ electron. Among them, the π electron is a free electron in the graphite layer, which is highly mobile and conductive. Graphitized petroleum coke has wide π electron band width and wide electron energy distribution range.
This structure allows the π electrons of graphitized petroleum coke to move freely throughout the aromatic ring, resulting in high electrical conductivity. In addition, the σ electrons in graphitized petroleum coke also have some influence on its electrical conductivity.
A sigma electron is a covalently bonded electron between carbon atoms and has some electrical conductivity. The σ-electrons in graphitized petroleum coke are mainly located in the graphite layer and play a role in stabilizing the graphite layer structure. When the number of σ electrons is higher, the structure of graphite layer is more stable and the conductivity is better.
