The difference between artificial graphite and natural graphite
Jan 10, 2024
The main difference between artificial graphite and natural graphite is their formation process and properties. Here are some of the main differences:
Formation process: Natural graphite is formed deep in the Earth's crust, and they are formed after a long time of high temperature and pressure. Artificial graphite is usually made under artificial conditions by heating carbon materials at high temperatures.
Structure: The crystal structure of natural graphite is a layered structure, each layer is connected by a weak van der Waals force, and the atoms in the layer are connected in the form of covalent bonds. The crystal structure of artificial graphite is also composed of multiple graphite layers, but their structure is more regular and uniform than that of natural graphite.
Properties: The hardness of natural graphite is low, and it has good electrical conductivity, thermal conductivity, lubrication and high temperature stability. Artificial graphite, because it is more uniform, has higher hardness and mechanical strength, and usually has higher purity and better physical and chemical properties.
Application: Natural graphite is mainly used in pencil lead, lubrication materials, lithium-ion batteries and other fields, while artificial graphite is more widely used, including high-temperature materials, electrode materials, composite materials, carbon fiber and other fields.
It should be noted that both artificial graphite and natural graphite belong to the graphite group of substances, and they have many similar characteristics and applications, but there are some differences.
