The presence of pores inside graphite blocks is typically attributed to factors such as the volatilization of gases during preparation, material flow, and crystallization. During the preparation process of graphite blocks, some gases or volatile substances may become trapped within the graphite structure, subsequently forming pores as the graphite block cools and solidifies. Additionally, variations in temperature, pressure, or other parameters during the preparation process may also result in the release of gases and the formation of pores. In some specific cases, pores may also arise due to defects or incomplete crystallization during the preparation process.
