Synthetic graphite is a form of graphite that is manufactured through the graphitization of carbon-based materials, such as petroleum coke or coal tar pitch. It is engineered to possess specific properties and purity levels. Here are some specifications and properties associated with synthetic graphite:

1. Lubricity: Synthetic graphite exhibits good lubricating properties due to its layered structure and low friction coefficient. It is used as a solid lubricant in various applications, including high-temperature environments, where traditional lubricants may fail.

2. Chemical Stability: Synthetic graphite is chemically stable and resistant to most chemicals, acids, and alkalis. It maintains its structural integrity and performance even in corrosive environments.

3. Mechanical Properties: Synthetic graphite possesses excellent mechanical properties, including high strength and stiffness. It exhibits a low coefficient of thermal expansion, providing dimensional stability over a wide temperature range. These characteristics make it suitable for structural applications and components subjected to mechanical stress.

4. Thermal Stability: Synthetic graphite retains its structural integrity even at high temperatures. It has a high melting point and can withstand extreme heat without significant degradation or structural changes.

5. Purity and Impurities: Synthetic graphite can be manufactured to achieve high levels of purity, with minimized impurities such as sulfur, ash, and metals. The purification process ensures that the graphite meets specific application requirements, particularly in industries where purity is critical, such as electronics and semiconductor manufacturing.

It's important to note that specific applications may have additional requirements or specifications for synthetic graphite, and these properties can be further customized or optimized to suit particular industrial needs.
