Artificial graphite is similar to polycrystals in crystallography. There are many types of artificial graphite, with diverse production processes. Broadly speaking, all those produced by carbonization of organic matter and subsequent graphitization Graphite materials obtained after high-temperature treatment can all be collectively referred to as artificial graphite, such as carbon (graphite) fibers, pyrolytic carbon (graphite), and foamed graphite, etc.
Narrowly speaking, artificial graphite typically refers to a solid block material obtained through processes such as batching, kneading, shaping, carbonization (also known as calcination in industry), and graphitization, using low-purity carbonaceous raw materials (like petroleum coke, asphalt coke, etc.) as aggregates and coal tar as binder. Examples include graphite electrodes and isostatic graphite.
